In Series 3 he tells Chandler, "No thanks, I'm 29" when offered chocolate milk; in Series 4 when the guys try to party without Gandalf they all say they're 29; and in Series 5 when he's trying to reconcile with Emily, he says either he does, or he would get divorced for the second time before age 30.

It says on Mary-Alice's tomb stone that she died on September 26th 2004, which was a Sunday, yet in the first episode, she says that she died on a Thursday.
