There's a bathrom on the rise.

The story:

I was spending the night with my then boyfriend when we got on the subject of wrong lyrics. I told him how many people though "Bad moon on the rise" was "bathroom on the right." We talked about other songs, and we got on a different subject.
Later, we were eating something that upset his stomach, and he really needed to go to the bathroom. He got up running, then sang as he got to the door, "There's a bathroom on the right!" and ran in!
