Back in elementary school, there were always a few “dirty nursery rhymes” going around such as “Miss Suzy Had A Steamboat” where there were constant references to sex and profanity, yet no “curse words” were ever mentioned.
This video of “The Assumption Song” is basically another one of those tunes. It’s not dirty unless your mind is.
Lines like “and then she’d bend over and suck on his- candy” at the 1:16 mark are pretty funny to blast on some loud speakers. The animation, although very simple, make it easier to visualize the song.
If you listen closely, you’ll notice that the only time that there is actually a couplet of rhyming words is at the very end.
