I once had a trash can as a girlfriend.
I was ready to break up with her, but all she had to say was, "Please don't dump me!" Then I said, "Sorry, I'm ready to take out the trash."
Hey, you absolute melon! The dude's girlfriend is a trash can, get it? So when she says, "Don't dump me," it's a pun because he's literally taking out the trash. You probably wear a helmet when you eat soup, don't you?
