Find me a website with a list of puns Radio 1 DJ Judge Jules has used
on his show and/or during sets (if you need clarification as to what I
mean I don't think you should be answering this!)

I would email him at his site and ask that he post it in his Q&A section.

That way you get the info directly from him instead of a second-hand
source on the net.
