@colon_closed_bracket dominating as I enter the thread:

I remember the really long lame shaggy dog story ones ending in
“… never cross the road while the green man’s flashing”
and
“… 9 out of 10 tramps prefer cornflakes”
Or something like that.
Years later I was told a tortuous one that ended with “…so Hans that does dishes can be soft as Gervais with mild-green hairy lipped squids”.
Yeah. School jokes are shit.
