One of the questions I get asked the most often is thusly...
"Who is the biggest wanker - George Bush or Tony Blair?"
Let´s perform a scientific analysis of the available evidence.
On Google, a search for "Tony Blair is a wanker" gives us 493 results.
"George Bush is a wanker" gives us 722 results. Ergo, Bush is a bigger wanker than Blair.
Right now, there are no matches on the entire internets for "George Bush is a bigger wanker than Tony Blair", so I am pleased to be able to place the first one.
However, using the same technique, you will find that Blair is considered to be a far bigger arse than the monkey faced boy king. Incidentally, Google is wank (6 matches).
