Retired Philadelphia 76ers star Allen Iverson appeared in a new Reebok commercial, where he talked about pants. The commercial, a parody of Iverson's infamous "practice" rant, also featured Shaquille O'Neal, Shawn Kemp and Lil' Duval.

Iverson makes his surprise cameo near the end of the ad, spinning around in the barber chair and incredulously asking why they're talking about pants, not the game.

"We talkin' about pants?" Iverson asks as he abruptly exits the barbershop.

The video is a spoof of Iverson's rant about practice during an interview.

Iverson, 38, had his No. 3 jersey retired on Saturday by the Philadelphia 76ers. The future Hall of Famer admitted the experience felt surreal.

"It's kind of like, it's basically bittersweet," Iverson said, via USA Today Sports. "It feels good, you know, but some part of my heart hurts because I realize and understand that it's over. ... When I come into the arena, I'm stepping out onto the basketball court with the street clothes on. And I know I'll never be in a uniform again."
