I heard this one the other day, after not hearing it for a few decades, and now it's in my head every time I go shopping. I might as well put it in your heads, too.
Bum Bum Bumblebee, Bumblebee Tuna,
I love Bumblebee, Bumblebee Tuna,
Bum Bum BUmblebee, Bumblebee Tuna,
Love my sandwich made with Bumblebee.
