what's the last thing you laughed at (chuckles don't count)

I have this older coworker who's known for rambling half coherently and constantly humming to himself.

A few days ago in the break room he was talking at me while I tried ignoring him on my phone. He said "My friend tells me humming to yourself all the time is a sign of senility, but I think that's a leftist conspiracy because I'm still sharp as a tack!"

I had to get up and go to the bathroom to laugh my ass off.
