Wanda Sykes, Shaquille O'Neal

Shaquille O'Neal is 19 inches taller than Wanda Sykes, but the pair made the height difference work to tackle holiday shopping on a tandem bike.

The video is a third installment of the American Express "Shop Small" campaign with O'Neal. O'Neal previous taped clips with Kendrick Lamar and Jeremy Piven.

The Bay Area bike shop O'Neal and Sykes visited is Berkeley Cycle Works in Berkeley.
