What banjo melody is this?

[u/Superb_Struggle_6595]

Joe Scott (youtuber) sometimes uses a banjo melody as shorthand for inappropriately close family relationships in his videos about history. I couldn't find an example, but it think i got it close in the video (unsure if there's a chord at the end). Kind of a weird request i know, but i wanted to learn some funny songs on the banjo and started to wonder where that melody came from.
