Don't know whereabouts you live, but Alumni Hall at the West Town Mall here in Knoxville had a whole rack of orange pants last Saturday before the UC game.
Here is a link to get them at Pennington and Bailes. Alumni Hall got the leftovers and unless you wear a 38 or 40 you are going to be out of luck there. MS McClellans carries Pennington and Bailes but they are running low on sizes as well. I was looking for some myself and spoke to the guy at Pennington and Bailes and he said they only initially made about 100 pairs of these pants and he was not sure on the time frame to make more of the pain orange but they would probably be 2-3 months out. If you do find some just note that they only come unfinished in a 37.5 length so you will have to get them altered to fit. Mine are at the tailor right now and I am hoping to get them tomorrow in time for the game! GBO V,B
EDIT: If you go to that website be sure to call and verify they have the size before you place an order because their system is not real time so just because a size is listed does not necessarily mean that it is available.
Can't get the exact ones Dooley is wearing because they are only making them for him. I believe I read/saw/heard somewhere that they may be making some cotton versions for the general public to buy, but Dooley's are wool I believe.
