Dad # 4 - Gyles Brandreth

Pros:
* I already have a foot in the door with him
* He holds the world record for the longest after-dinner speech at over 12 hours long
* He owns a teddy bear museum

Cons:
* I believe he still has those terrible jumpers hidden somewhere
* He's so busy, I doubt he would be home very often
* He has been known to cross-dress on stage
