Until quite recently I thought that Tom Petty and the Heartbreakers "Running down a Dream" was called "Running Down the Drain" For years while hearing it I've been picturing a little man trying to resist getting sucked down a drain in the kitchen sink!
A childhood belief about misheard lyrics

others believed things like this
- i thought that when you were in the bath you would get sucked down the drain— blake
- I used to think running for president involved actually running somewhere.— Artimage
- I use to believe the sound that a car made when it was running low on gas was what they called horse power...— Bianca
- how many us believed you would go down the drain with the bath water? I did!— Amy
- I used to think a drain pipe in my backyard led to another world.Anon
- I used to believe that once you pulled the plug in the bath a shark would swim out of the drain and eat you.— Amy
