What is it with my son?

Not to get too graphic here, but he refuses to do #2 on the potty. He has been perfect about potty training for like 3 weeks now, no accidents or anything....except for that. We'll find him in a corner or behind the desk chair and we have to race him to the toilet. Just now I heard him in the dining room, I look over there and sure enough. Red faced and all. So I tell him he needs to go potty, he screams no, ducks under the dining room chair, because after all, I can't see him under there. So I go to get him, bring him into the bathroom tell him to go potty, and he says "Oh. This." Yes son, that's where you go 5 -10 times a day everyday....not anything new. So he gets on and it's like I'm torturing him. He screams and cries and begs to get off, tells me he's done, anything to get off. I don't get this!?! Any advice? He doesn't act scared, and doesn't tell us he's scared. He finally will calm down enough and sit there until something happens. Right now he's singing. Why can't he just go there in the first place?

Whoo hooo!
