I have a son who likes to think of himself as the self-appointed king of random. I don't know how funny any of it is (I'm an old guy now so my funny bone probably needs a marrow transplant), but he keeps himself entertained.

Not sure why people looking lost and confused at him is entertaining, but hey, to each his own. I've always found it to be funnier when people are in on the joke rather than not. And if you have to explain why it's funny, well then you might as well give up and move on.
