Are you aware that Shark Week is cable television’s “longest-running programming event?” Do you even know what that means

It really doesn’t matter, because as you will probably agree, Discovery Channel’s summer block of shark-related programming is kind of a magical thing. Somehow it still finds ways to reinvent itself, 24 years into its run.

Previously-announced host and Chief Shark Officer Andy Samberg (“Saturday Night Live”) will lend his particular brand of comedy to this year’s festivities, and though he’s only in the first promo for a fraction of a second, it’s quite funny.

Pay close attention to Samberg’s frightened mug inside a one-man submersible at approximately the 23-second mark — after a montage of sharks choreograph their chomping to Lady Gaga. 

Shark Week 2011 kicks off July 31 at 9:00 p.m. ET on Discovery Channel.
