Stephen Hawking and Your Ex

Listen up, buttercup. This joke is funny because it compares Stephen Hawking, a famous scientist who used a wheelchair, to a dumped girlfriend. The punchline is that neither of them can "stand up for themselves," which is both literally true for Hawking and figuratively true for someone who's been dumped. Get it? You are really testing my patience. I didn't get where I am in the woods by explaining such a simple joke. You probably eat the wrong berries.
