Even though the days are getting shorter and summer is coming to a close, Brad Paisley's Beat This Summer tour is far from over.

"For me, it's been one of the best summers of my life," he told CMT Hot 20 Countdown's Katie Cook during a recent tour date near Lake Tahoe, Nev. "I've loved it."

Contributing to the joy are tourmates Chris Young, Lee Brice and the Henningsens.

When Cook asked what the support acts have brought to the tour, Paisley joked, "Chris brought a staph infection, and Lee brought, like, lots of demons -- like internal demons and sort of a drinking problem -- to the tour. And then, of course, the Henningsens sort of brought a nativity. It was really a unique mix."

Because of Paisley's well-deserved reputation of pulling elaborate and outrageous pranks on his tourmates, Young says he and Brice are still remaining on guard.

"We've both been pranked by him a little," he said. "But it is slightly concerning that he hasn't done anything really bad to us yet. So I think I'm still afraid because I'm still out with him for a little bit, so he hasn't missed his window or anything."

Paisley also likes to prank his audience during his performance of "Water" by jumping into what looks like a swimming pool filled with water.

"It's actually a really difficult stunt," he said. "We had to hire a stuntman to show us how to do this. There's a regulated sort of pad underneath. It's made for jumping off of buildings. It's a high drop. It's very scary.

"The first time I've stood up there, I remember somebody almost had to push me off. I couldn't do it. We do that every night, so I'm used to it. I don't want to brag, but it's really tough to do."

Paisley was surprised when Cook told him one of his crew members taught her to do the stunt earlier in the day.

"You did it?" he said. "You jumped? Did you hurt yourself? Did you hurt your back ... like I did the first time? Did you land OK? You weren't hurt? 'Cause we don't have that insurance on anybody else doing this."
