What do you do with a dog that has no legs?
Take him for a drag.
Alright, listen up, chucklehead! So, you got a dog, right? But this ain't no ordinary dog; this one's missing its legs. Now, instead of feelin' sorry for the poor mutt, you take it for a "drag." See, it's a pun, because when you drag something, it slides along the ground. Bet you didn't know drag can mean pull something along with effort or difficulty. That's like, vocabulary 101, ya bonehead!
