It's not often I get to throw around board game references, so you better believe I'll take one when I can. Do you remember Trouble, the game with the "Pop-O-Matic" bubble? That sound echoes in my head from childhood. Well, it turns out Supertramp took notice of that sound, too, when they were recording 1979's Breakfast In America. Among other sound effects, "The Logical Song" uses the "pop!" of the Pop-O-Matic bubble!
