A song my dad would always sing when he felt like being a dork more than usual:

Ay yay yay yi
I am the Frrrito Bandito!
I love Fritos cornchips, I love them, I do
I want Fritos cornchips, I'll take them from you
Ay yay yay yi
I am the Frrrito Bandito!

He always attributed it to commercials he heard as a kid which were discontinued because they weren't politically correct. (A Hispanic Hamburger Burglar type insinuates all Hispanics are thieves was the reasoning.)
