Ann Althouse has an interesting post up about this:
Which is a poster I saw last night at the movie theater.
In her own comments, someone takes her to task for the gender asymmetry issue. ""Domestic battery is funny as long as the right person gets battered?"
"It's hard to write and perform comedy, so it couldn't possibly ever be that X is funny as long as Y. The post is talking about ways something that's not funny in real life can be funny."
Puts me in mind of the legendary last words of Edmund Kean: "Dying is easy. Comedy is hard."
So maybe you can milk some chuckles
out of a ring with brass knuckles.
More likely it will fall flat.
Like this... kersplat!
