a childhood slogan

i recall the days when mean kids would say to unpopular kids stuff like 'roses are red, violets are blue, my mom smells like sunshine, your mom smells like poo.' technically, you could finish the invective with anything that rhymed with blue, but in reality approximately 98% of insults delivered using this framework finished with 'poo'. 'your dad forgot to shower, now he smells like poo', 'when i look at your face, it makes me think of poo'. you get the picture.

but violets aren't blue, they're, well, violet right?
