WARNING: The following contains minor spoilers for the first two episodes of Marvel's WandaVision, now streaming on Disney+.

Set in an idealized suburban community right out of a classic sitcom, Marvel's WandaVision pays tribute to those television roots in opening sequences that give nods to what came before. For example, in the series premiere, Paul Bettany's Vision carries his new bride, Wanda (Elizabeth Olsen), across the threshold of their new home and, in a wink to The Dick Van Dyke Show, simply passes through the chair in his path.

However, the second episode, which homages Hanna-Barbera's animated opening credits for Bewitched, goes a little deeper with a handful of comic book Easter eggs -- one of which is tragic, and another is downright icky.

WandaVision Episode 2 Bewitched parody

Just like the iconic Bewitched intro, WandaVision's opens with a shot of the moon before replacing Elizabeth Montgomery's Samantha Stephens with the show's stars, soaring above the rooftops of idyllic Westview before beginning their respective days -- Vision to the office, and Wanda to the supermarket. Along the way, the sequence delivers its four Marvel comics references.

Grim Reaper, an Old-School Avengers Foe Killed by Virginia Vision

WandaVision Grim Reaper Easter Egg

As Vision phases through the floor from the bathroom to the living room below, we catch a glimpse of objects between the floors: cartoonish standards like bones and a spider web, and then something resembling a hat or helmet. The latter, and perhaps the former, belongs to Grim Reaper, aka Eric Williams, brother of Simon Williams, aka Wonder Man, the villain turned hero whose brainwaves were used to program Vision.

It's a long and complicated story, but Eric's brother Simon was transformed by Baron Heinrich Zemo into Wonder Man in order to exact revenge against Iron Man and the Avengers. When Simon was killed (don't worry, he got better), Eric became the scythe-wielding Grim Reaper, and launched his own crusade against Earth's Mightiest Heroes. In Vision, the acclaimed 2015-2016 series by Tom King and Gabriel Hernandez Walta, Grimp Reaper attacks after learning the synthezoid has created his own family -- wife Virginia and children Vivian and Vin -- and is living a happy life in the suburbs. Vision isn't home, but Virginia leaps to her family's defense and beats Grim Reaper to death before secretly burying his body in the backyard. It's that act that begins the unraveling of the "perfect" family.

Wonder ... Oats? It's a Reference to Longtime Avenger Wonder Man

Wonder Man

As Wanda stands in the supermarket aisle with "Geraldine" (Teyonah Parris), a trio of ads are seen on the far wall. Although the first is partly obscured, it appears to be promoting Wonder Oats breakfast cereal, which is almost certainly a reference to the aforementioned Wonder Man. Recruited into the Masters of Evil and imbued with a range of superhuman abilities, Simon Williams was believed killed in a fight against the Avengers (he was instead merely a "deathlike coma"). His memories and behavior patterns were then used to program the synthezoid Vision. Wonder Man was later revived, and joined the Avengers; because of their unique relationship. Vision and Simon Williams are often considered to be "brothers."

Auntie A's Kitty Litter Is a Nod to Agatha Harkness and Her Familiar, Ebony

Agatha Harkness and Ebony

On the right it a poster for Auntie A's ("Kitty Litter That Lasts"), a nod to Agatha Harkness and, more specifically, her feline familiar Ebony. A powerful witch who served as the governess of Reed and Sue Richards' son, Franklin, and later mentored Wanda Maximoff, Agatha played a central role in the long, bizarre history of Vision and Scarlet Witch's children.

There's long been speculation that Kathryn Hahn's WandaVision character, wise-cracking Agnes, is actually Agatha Harkness in a different, and potentially more sinister, role. This nod does little to dispel that.

There's No Easy Way to Explain Bova Brand Milk (Sorry)

Bova and Quicksilver

We saved the milk ad for last in hope that you'd already finished breakfast. You see, in Marvel comics, Bova Ayrshire is a Guernsey cow who was genetically engineered by the High Evolutionary. Like the rest of the New Men, she's a humanoid creature who walks, talks, wears clothes and, apparently ... sells ... her ... milk?

Bova served as midwife in the birth of Wanda Maximoff and her twin Pietro, better known as Quicksilver.

Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau, and Kathryn Hahn as Agnes.
