Just been flicking through the North Wales Bouldering guide as I may be paying a visit to Llandudno in the near future (and am too shit to do anything in the Cave of Justice) and noticed that on pg202 there is a picture of Mark Katz with the caption...
"Leo Sayer, Papa Big Punch V8+, Angel Bay/Porth Dyniewyd, Photo/Ffoto: Simon Panton"
...presumably on the basis of "Shit isn't that.."
What other jokes or references have you come across in guide books?
