I think the lyrics were "smash them! bash them! now they're history!" with an italian accent. Probably a real song with different lyrics. It has the singing pizza elmo tune found here. I have a picture of something like play-doh monsters getting smashed in my mind but I might just be crazy.

That jingle is for the Grape Escape game. The commercial for that game is on this site.

Hey, yeah that's it! Thanks for the reply.
