Funny Or Die's contribution to the general shark madness that this week brings is Sharklumbo, which, they explain, "Is a shark and it's also Peter Falk as Columbo." You know what? The Asylum's Sharknado 2: The Second One was similar overexplanation.
Kevin Pollack's Peter Falk impression makes this whole thing work. Also, this take on Columbo's classic "One more thing" bit is spot on. I guess it might be NSFW if you don't like extremely poor CGI violence.
