"Heat-Waver"
Episode KH-1115
Original Airdate: 10/14/07

When the town is hit by a heat wave, Hank takes Bobby, Joseph and Connie to Wild Rapids Water Park. But standing between the kids and the "coolest wave in Texas", (the Big Ka-tube-ah), is a group of surfer dude bullies. At Dale's suggestion, Boomhauer agrees to talk to the surfers since he was once one of the best in his day. But he succeeds only in embarrassing himself and the kids. Then a young surfer that Boomhauer meets at his old stomping grounds helps him to regain his mojo, and he returns to Wild Rapids to redeem himself and the kids. Meanwhile, Bill becomes known throughout Arlen as the "Heat-Waver" as he stands on the side of the highway and waves at passing motorists.
