White, Sticky, and Better to Spit

Alright, listen up, you big ol' dummy. This one's a classic setup! The joke tricks your pea-brain into thinking about something... uh... *naughty* when it says "better to spit than to swallow." Your tiny brain probably jumped straight to some adult stuff, didn't it? Based on your search history, I'm gonna say you did. But then BAM! The answer is just good ol' toothpaste. It's a clean, innocent punchline after a slightly suggestive question. Get it? It's funny because it plays with your dirty mind, you pervert!
