Three lifelong buddies (one not so bright) were returning from a day of mountain biking in the Rocky Mountains. The not so bright buddy was in the back of the truck to better enjoy the mountains.

Heading around a rather tight turn, the truck veers off the cliff and plummets into a lake just below.

After just a few seconds, the two buddies in the truck cab break the surface with a gasp of air. To their horror, they realize their not so bright companion was still under water and they both immediately dove down to rescue him.

They pulled him to the surface and after a coughing fit asked him why he hadn't swam to the surface. With an annoyed look on his face, the not so bright buddy says, “I couldn't get the tailgate open!”
