Not even going to lie, I still get this jingle stuck in my head from time to time. No clue what even triggers it most times. There was a radio spot for Schlotzky's deli that I heard once many years ago and has stuck with me. "Come on down to Schlotzsky's, come down to Schlotzsky's deli, put a smile on your face and a Schlotzsky's in your belly".
PS: Schlotzsky's is a bitch to write out.
