I always have a song stuck in my head. Either I heard the song or someone says something that reminds me of a song.
Like I made a mistake earlier and had to send something to our CPA (they are younger guys so they have a sense of humor) so I said......Oops, I did it again. Then said....Hope this song doesn't get stuck in your head.

He responded and said....on a side note now I have Britney Spears wonderful voice in my head this morning.
