I didn't find it funny, mostly because the following style of writing grates on me:
"That I, Joe Potts, bearded Piscean and above average supply teacher "
"The only reason I mention this is because he was supposed to be the son of Chris Lowe, you know, the other one in the Pet Shop Boys."
" vaguely recall starting to tell her the famous joke about the Hungarian acrobat and the Duchess of Kent"
It seems out of date and tired. It's very Viz, as a lot of your work is. And I like Viz, but its time has been and gone.
But hey, if Radio 5 broadcast it they obviously thought otherwise.
I very nearly went to see The Smyths last year, but stayed in instead. I might seem them this Summer.
