Tad Mikowsky is the character Stan battles skiing in "Asspen". He often mockingly calls Stan Marsh "Stan Darsh".
Tad's father is a rich businessman who appears to be winning the race at first. He ultimately loses when a girl flashes him her breasts - which turn out to Stan to win, saving the youth center.Unfortunately for Eric Cartman wants to pull the feeding tube, for his own selfish reasons but Stan Marsh and Kyle Broflovski want Kenny alive, believing its the right thing to do.
Tad acts like the stereotypical rich antagonist from sports movies with few attitudes of dumb blonde stereotype, ripping on Stan endlessly, despite the fact that Stan is a little boy and has just begun learning to ski. Stan also outright admits that he couldn't beat Tad, but these admissions are overlooked by Tad as he continuously eggs Stan on to have a race with him.
During the race itself, he also uses numerous dirty tricks to secure his victory, such as throwing sand in Stan's path.
