I went through a stage
where I had a UV pen, and I used it to draw a beard and glasses on the Queen and a speech bubble on every character on the back so they were saying expletives. On every single banknote I had until the pen ran out.

Seeing people react to the Queen is one thing, but when they saw Michael Faraday and Charles Dickens saying 'Pissflaps', their face was a picture.

ahh but
a UV pen is one thing, but using spunk is a whole different league. When you hand someone a banknote, you get the chance to have a titter and maybe tell them whatever it is that's fluorescing.
