Nathan Fillion's Butt is Super-Distracting in New 'Muppets' Promo

Just how "adult" is ABC's "The Muppets"? Enough that one of three star-studded promos for the revival is thrown off-track when Miss Piggy can't stop staring at Nathan Fillion's behind, just off-camera.

Debuting this morning on USA Today and other outlets, the television spots also include appearances by "Scandal" star Kerry Washington and "The Middle's" Patricia Heaton.

Premiering Tuesday, Sept. 22, "The Muppets" will take a mockumentary-style approach to the beloved characters, moving beyond the theater and into their personal lives. And, as these promos suggest, like the original "Muppet Show" this revival will feature plenty of celebrity cameos.
