This thread is retarded, you don't have to say it.
I said it for you, but having that been said: Which commercial annoyed you the most in 2005? For me, it had to be the one with Taylor Dent & Andre's Spawn, I forget the kid's name, it drove me insane during the French Open.
It doesn't necessarily have to be tennis related, it can also be a commercial or advertisement that ESPN insisted on playing 50 + times a day. Like the Nasdaq commercial during Miami or World On A String commercial a few years ago.
The commercial for the Dubai tournament on Eurosport (with the WTA players saying "I love Dubai" etc.)
It also qualifies for the most annoying commercial of 2004 because they have been showing it constantly for TWO YEARS now on Eurosport (with slight variations)!
