one I randomly came up with: "Mom, the booger wall, just got some new names. So we got the pee wall, the poop wall, the earwax wall, the pp snot wall, the throw up wall, and my personal favorite name, yummy."
to put your mind at ease, it's the "c". the most recent ancestor of "scent" is "sent", the c started cropping up for some reason around the 1600s in the verb "senten" which gave us the noun.
