Ugh ! The agony !

Why do I do this to myself ?? What, you ask ? Why do I sit here singing goofy songs over and over in my head ! I realize I'm a big MAGOO and that's why this consistently happens, but geez ! There's no rhyme or reason as to which songs pop into my head either. Today it's "Rain drops keep falling on my head".... then I busted into "The Hustle" ! That song frequently comes to mind and I generally like to whistle it. Beyond the goofy songs, I find myself singing jingles or radio call letters ! I'll be singing along, and stop and say "what were you thinking" !!! Sheer craziness and a little bit of boredom, I guess.....
