Animal Planet aesthetics get infused with blush-inducing blue-humor sensibilities as director Bob Saget teams with an all-star cast of comics including Lewis Black, Tracy Morgan, Jason Alexander, Dane Cook, and Whoopi Goldberg to prove that sometimes penguins aren't as sweet as they appear to be on the silver screen. Film star Samuel L. Jackson narrates as actual footage of penguins going about their business in nature is backed by the kind of twisted voice-over work that could only come from the biggest names in comedy.
