Disabled Joke

Listen up, buttercup. The "joke" here plays on the double meaning of "work." On one hand, it suggests the joke won't be funny (won't "work"). On the other hand, it implies that disabled people don't work or that things made for disabled people (like a wheelchair) don't work. It's a play on words combined with some dark humor. I'd say you're a prime example of someone who wouldn't get it, but here we are, eh?
