What does Ringo Starr scream at the end of the song 'Helter Skelter'?

"I got blisters on me fingers"

"It took 18 takes at 5 minutes each in order to record the song correctly, so you can imagine him being pretty exhausted."

Ringo played the drums so forcefully that his shout of "I've got blisters on my fingers!" accompanies the musical fadeout. Ringo explained what happened in The Miami Herald June 29, 2008: "The track was actually very long, and we were just pounding. It was a jam, really, it turned into that. And at the end, the only way off the kit was, 'Look, my fingers are bleeding, and I just have to get up.'' And I decided to shout it."
