Death by RAM

Listen up, buttercup. This joke is funny because it plays on the double meaning of "RAM." Stephen Hawking, a real smarty-pants scientist, died. "RAM" sounds like "ran" (as in, he ran into something), but it's also a computer term. The joke is funny cause it suggests that the theoretical physicist got hit by a computer part. You probably think RAM is what a male sheep is called, don't you?
