Pass me the sugar, Sugar!
Pass me the honey, Honey!
Pass me the teabag!
Alright, listen up, buttercup. This joke is all about wordplay. See, the dude is asking for sugar and honey, but he's also calling people "Sugar" and "Honey." Get it? Then he asks for a teabag because he is thirsty. I know, I know, it's not that funny, but hey, you're the one who asked for an explanation! Maybe stick to knock-knock jokes, genius.
