Potty Training HELL

I know its time.
I started trying a few weeks ago, I would put some shorts on Stewie without a diaper and he would complain when he felt "HOT" down there... so I knew he peed.

I thought that would entice him to tell me before hand so he could use the potty.
He's used it a few times, here and there, but not without me sitting him on it for a half hour at a time until it comes out.

Today I decided to just do the underwear, and I figured, just one time he pees and it will be all over and the next time he will tell me he wants to go on the potty before he wets himself again. but according to him, its alot funner to pee himself several times, get my awesome reaction, and laugh about it.

I know its basically only day 1 in the official race to potty train my 2 1/2 year old son. But this ONE day has basically driven me to want to run away. How do you mothers do it? He peed on the coffee table twice, the rug once, then sat on the potty til i got more underwear, then peed when he stood up.....

Its like its a little ha ha joke to him.
But hes gonna be 3 in November. Most boys are trained by now right? Or am I doing this all wrong? One friend says Im not trying hard enough, one says let him tell you when hes ready. But I ask him everyday if hes gonna use the underwear and potty today and he says "nope, diaper mama!"
I had to actually force it today, and all I get in return, is spot shot all over myself and the carpet, a pissy windexed coffee table, a load of laundry, and a HAPPY DIAPERED child, oh and my headache...
Did I mention my husband just called and said he wouldnt be home til almost 7 tonight?

sigh.....
