VIDEO SCOOP: Kevin McHale pops a wheelie on 'Glee'!

Kevin McHale, who plays the wheelchair-using character Artie on the hit TV series "Glee," is going to have his big moment in an episode titled "Wheels," which will air in three weeks. 

And he's gonna have a lot of wheeled company.

According to critics, this promises to be one of the most heart-warming episodes yet, with Will encouraging all the "Glee" kids to perform in wheelchairs. 

"It's probably the most serious," Kevin told us. "... You definitely see sides of people that you probably are not expecting. ... There are four huge story lines going on, love triangles switching up. And everyone gets in wheelchairs at some point." 

"I can't even explain it," he admits, adding that: "You see the heart in some people you might not expect to have a heart."

And expect more of Kurt and his dad getting closer. Hooray! 

We asked Kevin for his green tip (he was on the Sunday night green carpet for the Environmental Media Awards) and his advice was to take shorter showers and turn the water off when you're brushing your teeth. 

But no, he doesn't follow Ed Begley's toilet-flushing tips.
