Can't have a smoke with my girl after sex, she's asthmatic.
Plus, she's too young to smoke.
Listen up, genius. The joke is that the dude can't smoke with his girl after sex because she has asthma. But then there's a twist: she's also too young to legally smoke. So, it's not just about health, it's about age too. It's funny because it's messed up... like your search history.
