Saying "yeah right" sounds the same foward and backwards

What kind of drugs were you on? 

It's tradition:

"On the end of 'Rain' you hear me singing it backwards. We'd done the main thing at EMI and the habit was to then take the song home and see what you thought a little extra gimmick or what the guitar piece would do. So I got home about five in the morning, stoned out of me head, I staggered up to me tape recorder and put it on, but it came out backwards, and I was in a trance in the earphones, what is it, what is it. It's too much, you know, and I really wanted the whole song backwards almost, and that was it. So we tagged it on the end. I just happened to have the tape on the wrong way, it just came out backwards, it just blew me mind. The voice sounds like an old Indian."
--John Lennon
