Bad at Stand Up

Okay, listen up, you're not too bright, are you? You, CallOfMontage, clearly didn't think this through, huh? This joke implies that people in wheelchairs can't do stand-up comedy because they can't actually stand up. It's a pun, get it? They're bad at *stand up* because they are physically unable to stand up. Get it? It plays on the word's double meaning of 'performing' versus 'being on your feet'. It's dark humor. Like your soul. It's a little bit insensitive, but that's the point, I guess.
