can't remember anything about this song other than how to play it

there's this short riff I've been playing on my bass and guitar for a while and I can't remember anything about it, it might be from a cartoon or something of the sort, it could possibly be shifted a fret or more up Im really not sure, and it has a jazzy spy sound to it, if anyone could figure it out that would be awesome, I've got an earworm, if this isn't the right sub for this I totally understand thanks in advance
