Context: My informant went to elementary school in the ‘70s and sang me this song he said was used to pick on other kids you didn’t like. He told me it was a song that everyone knew, and everyone was afraid to have it sung to them. He remembers it today because of how funny he thought it was as a child.
Driving down the highway, highway 64
[Name] ripped a big one, it blew out the door
Engine couldn’t stand it
Engine blew apart
All because of [name]’s supersonic fart
My thoughts: This definitely sounds like a song you would sing to make fun of friends and enemies. I hadn’t heard this song, and no one my age that I’ve talked to knows this song, so it must have gotten less popular as the years went on. I looked it up and found different versions for different regions. Here’s a link to an archive by hosted by Straight Dope where you can find different versions of this song, and other “naughty kid nursery rhymes” https://boards.straightdope.com/sdmb/archive/index.php/t-271331.html
“He who smelt it, dealt it.”
This saying is a comment in response to an accusation that one has passed gas, and is more or less a way of saying that the accuser is the guilty one and only looking to place the blame on someone else to avoid the embarrassment of owning up to it. This phrase is usually used when in groups of three or more, and usually entails someone smelling a foul odor and calling the offender out on it. My informant said that one of his brothers told him this phrase when he was younger, as well as the follow-up phrase that “whoever denied it, supplied it.” It’s basically a way of humiliating each other and making light of a natural bodily function that is otherwise unseemly.
Theoretically it could be labeled as a proverb in that it implies that whoever brings up an unspoken problem is likely at fault for it, and the same can be said for anyone who denies having caused the problem. However, to this collector’s knowlege it doesn’t usually come up outside of the specific situation of passing gas.
Annotated: This saying was used as a joke with a double meaning in season 2, episode 16 of South Park, in which the protagonists were trying to find who was to blame for the recent trend of telemarketers taking advantage of elderly people by selling over-priced jewelry. The gold jewelry would be given to their relatives, who would sell it to the pawn shops, who would then smelt it down to be remade into new jewelry to be sold again. The joke was that the smelters were at fault for the entire scheme, hence “he who smelt it dealt it.”
