Me and my wife decided we would only smoke after sex.
I'm still on the first pack. She's up to 2 packs a week.
Alright listen up, buttercup. This joke is about a dude who ain't gettin' any action. He and his wife made a deal to smoke ONLY after sex. The punchline is that he's still puffin' on his first pack, while his wife is chugging through two packs a week. Translation: She's getting it on with someone else because, as we can tell, you ain't stepping up to the plate, which isn't surprising since you write bad jokes.
