Did you know that ASL is a dead language?
Yeah, nobody speaks it.
Alright, listen up, you chucklehead! This joke is about ASL, which stands for American Sign Language. The joke plays on the double meaning of "dead language." Usually, it means a language nobody speaks anymore, but in this case, it's funny 'cause nobody *speaks* ASL, they sign it! Get it? You probably don't because you can't even read, can you? But it's funny, trust me... or don't, I don't care.
