Leave All Your Crap In Canada

(I suppose I’m the idiot here. I’m driving my RV into Canada to visit a friend. After checking my passport, etc.)

Customs Official: “And is there anything in your RV that will stay in Canada when you leave?”

Me: *frozen with confusion*

Customs Official: “Like a gift?”

Me: “Oh! Yes!” *I list what I’m bringing my friend*

Customs Official: “Um, what were you thinking when I asked that?”

Me: “The contents of my RV’s toilet holding tank?”
