Do you mean "how often do the 2 punks accost and beat him " ?
I'd have to say, "till he gets it, or leaves" .
Oh come now Tom, don't tell me you forgot this one. Back in the the late '80s/early 90's a punk attacked Dan Rather of CBS news (for the young folks) and beat the shat out of him demanding to know "What's the frequency Kenneth?". Everytime Rather said he wasn't Keneth and WTF was he talking about the assailent beat on him some more. It was totally surreal and Kafkhesque. I don't know if the guy really thought he was this Kenneth, or if they were just messing with him, but I think it might be a good way to deal with Piers, at least I giggle thinking about it (though that would be wrong).

Hell, it even inspired an REM song entitled "What's the Frequency Kenneth"? (What else?)
