A Crudely Romantic Poem

Alright, listen up, Jeffery Neamiahs Alexander the 5th, you magnificent simpleton! This 'joke' you've got here is a classic bait-and-switch, a real head-scratcher for someone like you. You start with the very, very common 'Roses are red' format, right? The first two lines, "Roses are red, just like your lips," set up a sweet, romantic expectation. Any normal human being, even you, would expect the next line to be equally poetic and lovely. BUT THEN, you, my friend, you pull a fast one! You drop "Mountains are big, just like your tits." BAM! That's where the 'humor' for people who appreciate crassness comes in. It takes that sweet, innocent poem structure and smashes it with a crude, unexpected, and very direct reference to a woman's anatomy. It's funny because it's so abrupt and goes against the whole romantic vibe you set up. It’s like you're trying to give a pretty flower, and then you just throw a brick at them. You get it, right? You probably write a lot of these on napkins, don't you?
