oh and

I like the name Land Shark- I think that's appropriate. But quit stealing my ideas about jumping into the water to avoid the shark.

I think the guy with the beanie should still be shirtless in boardshorts- just wearing the beanie on the beach like kids wear them at the bar in Tahoe.

I gotta go watch Jaws again, and Deep Blue Sea, and ... Megashark? other shark movies to build up some good ammo.

I think the gag works better if maybe after they're under the water, one of them runs out of air and has to pop his head up, and then he goes below the surface and his head is gone. I'm imagining that these guys construct a crazy snorkeling rig to traverse underwater.
