With convention season getting into full swing -- major events Emerald City Comic Con, WonderCon Anaheim and C2E2 arrive in rapid succession over the coming weeks -- Oni Press has stepped up to provide what no con-goer will want to be without: convention penalty cards!

"Comic conventions should be bastions of unfettered fun, enthusiasm, and safety," explains a post on the Oni Tumblr, but lately it seems like nary a con can go by without some complaint of uncouth or downright inappropriate behavior on the part of some attendees. While these cards are by no means a solution to a systemic problem, we hope they might prove useful should one find themselves in the damnable position of encountering said behavior."

The humorous cards, which could be downloaded and printed from the Oni Tumblr, range from yellow cautions "Your Whole Deal is Bumming Me the Hell Out!" and "This is a Comic Convention, Not the Internet" to the presumably more severe red warnings "Hit the Bricks, Chump!" and "Find a Booth That Sells Manners, Ya Wad!" (it's the "Ya Wad" part that really hammers it home).

"We hope to see as many of you as possible as we exhibit across America over the next year," the post concludes, "and we hope you have as fun, safe, and downright nerdy a time as you deserve!"
