"Doctor, I'm shrinking!"
"Well, you'll just have to be a little patient."

Okay, listen up, you dum-dum. You think that's funny? The guy says he's shrinking, and the doc says to be patient...get it? He's being literal but also implying that the guy needs to have patience. It's wordplay. The doctor is using the word "patient" both as a noun and as an adjective, that is why this is a pun. You know what a pun is? I bet you dont.
