William Shatner has been in show business a very long time. You probably know him as Captain Kirk on "Star Trek," but you might recognize him first as Denny Crane from "Boston Legal" or Sgt. T.J. Hooker from the so-named show or as the host of "Rescue 911" or, if you're young or totally clueless, as the irritable father from "$#*! My Dad Says."
Of course, Shatner is the Priceline guy too. Over the course of a several-decade career, Shatner has pitched a ton of products, some of them more ridiculous than others. In one commercial, he even co-starred with a giant penguin, possibly the same one from "Billy Madison."
