Cleaning Songs Puns

I had a little mishap with a pruning saw in the yard and asked my wife to patch my finger up. She's a nurse, so I figured she'd dress my wound better than I could. She started off with cleaning up the cut with a betadine swab.
Wife: "This might sting a little bit."
Me: Yup. Yup that stings.
Wife: Sing a song. It'll take your mind off of it.
Me: "Roooooxanne, you don't have to put on the red light, Those days are over you don't have to sell your body to the night..."
Wife: sideways look
Me: "Roooooxanne, you don't have to wear that dress tonight, Walk the streets for money you don't care if it's wrong or if it's right..."
Wife: sideways look
Me: "You know who sings that, right?"
Wife: "Yeah, the Police."
Me: "Who and the Police?"
Wife: "Sting?"
Me: "Yes it does."

For all of my life, my brain has played a soundtrack. At all times, in all places, I hear music going through my head, from the moment I awaken in the morning until I go to sleep at night. I can only shut it off by listening to other music, watching a movie, etc. but it soon starts up again once the outside source of stimulus is removed.

Yesterday I was travelling. When I visited the restroom prior to boarding my flight, the the music in my head suddenly switched tracks from "I've Been Everywhere Man" (that got really old after the first hour. Oy!) to "Africa" by Toto. "That's odd", I thought to myself, "the music in my head usually doesn't switch tracks unless something has changed around me." I finished my business, cleaned up, stood up, and turned around to flush.

Then I saw it. There, emblazoned on the porcelain, was the word "TOTO". The manufacturer of the toilet. "Nice job, brain, funny, hah-hah," I thought to myself.

The song in my head came to an abrupt halt. Silence, for just one moment. Blessed silence. Rare for me. Then I realized. My brain was giving me time to digest the previous joke. Waiting for me to think I'd arrived at the punch line. Pausing for a beat before it delivered the next one. "Africa" started over again, telling me exactly why the DJ deciding songs in my head had picked this exact moment, this exquisite situation, this exact set of circumstances to deliver the internal Dad Joke of the year:

"Doodoo doo-doo doodoo do dooooooooo...."
