Listen up, buttercup. This here joke is funny 'cause it uses the classic "Knock, knock" setup. The punchline plays on "Little Boy Blue" and then twists it into "Michael Jackson." It's unexpected and kinda silly, which makes folks chuckle. You probably wouldn't get it, but it's like when you try to build with Lincoln Logs and just end up eating them.
