University College, Cardiff, late 1970's. To the sign in the gents' toilet which read, "Please do not drop cigarettes into the urinals", wags appended, "It makes them soggy and difficult to light again"

On condom machines in various pub toilets:

"This chewing gum tastes awful"
"Buy me and stop one"
"Not to be consumed on the premises"
"Retreaded for extra grip in the wet" Ahem... Sorry about that one, ladies
"This machine is NOT the one for drying your hands"


And my favourite from Mr. Rees:

"To be is to do - Descartes"
"To do is to be - Sartre"
"Do be do be do - Sinatra"
