I remembered that from somewhere... it's from a Bloodhound Gang song! Or the song was written due to that joke. I dunno.
Of course, being the Bloodhound Gang, the song is NSFW and potentially upsetting so I won't post a link. But if your curiosity is killing you, the title of the song is 'A Lap Dance Is So Much Better When the Stripper is Crying' and the lyrics are just as purposefully offensive as you would think from that title.
Anyway now for something completely different...
"You're going to the vet."
