While Big Show continues to show off his preparation for Wrestlemania through Instagram and Twitter posts, Shaquille O'Neal is getting ready for their rumored bout by...promoting doughnuts and cookies.

Despite Shaq's claims that he's working on a six-pack for his Instagram crowd, his latest move is a Krispy Kreme commercial promoting their new coffee:

In the ad, Shaq conducts a "blind" taste test where he tries to bribe contestants with a doughnut and a not-so-subtle smile.

Shaq is also a spokesman for Nabisco's Oreo Dunk Challenge contest, which challenges fans to come up with inventive ways to dunk the iconic cookie in milk:

Meanwhile, Big Show posted yet another tweet this week showing his workout results and calling Shaq out:

Looks like Shaq has some catching up to do if he wants to get shredded abs in the next six weeks.

Wrestlemania 33 will be live in Orlando this April. While a fight between Big Show and Shaq has not been confirmed, Show's constant taunting implies it is highly likely.
