Along the lines of others who said ya gotta love your grandkids when the songs stuck in your head aren't modern or classic rock LOL....

Try getting the new theme for Tomas Tank Engine and Friends called "Engine Roll Call" stuck in your head for a metric or full century and you'd give nearly ANYTHING to be able to sing something else to remove it!!!

There are often times I'll sing some Klaatu "Little Neutrino", when I'm in a "jugular" vein, I try to get some Alice Cooper or Ozzy going, but something about the kids songs that is so pervasive that sometimes it just WON'T go away....
