From this NYT interview:

Has your relationship with your penis changed?

I would characterize it sort of like a powerful interest group within a political party at this point. It used to be the entire political party.

I’m curious how your tour is going. You have a new album, “Aprés,” and you’re out there with the Stooges. You resolved in 2010 that you wouldn’t stage-dive anymore after you had a mishap.

I said that after doing a concert for Tibet at Carnegie Hall, which I did because Philip Glass asked me to. [Emph. added — Heathen] But yeah, I am a little impulsive, and Lenny Kaye was playing “I Want to Be Your Dog” too damned slow, and I just ran out of ideas and I thought, Well, let’s just stage-dive. Nobody caught me, because it was the Carnegie Hall-Tibetan-whatever audience. I was a little miffed. We’ve done two gigs this year, and I haven’t done one yet. Stages are getting higher and higher, and I’m getting older and older.
