Most Bizarre 'Lip Sync Battle' Ever? Josh Gad Makes Out With Johnny Galecki as Kaley Cuoco Watches

By
There's clearly plenty going on during Josh Gad and Kaley Cuoco's upcoming appearance on Spike's Lip Sync Battle.
In a new preview of the episode airing Thursday, the 34-year-old Frozen star performs the Divinyls' racy 1990 classic, "I Touch Myself," but things turn pretty weird -- fast. Gad inexplicably performs the number dressed as Donald Trump, strips down to shorts covered in money, then swings on a wrecking ball prop (probably the same one Anne Hathaway memorably took a turn on last April).
And just when you thought things couldn't get any crazier, Gad takes it to the next level. To the shock of the audience, the actor makes out with his competitor's Big Bang Theory co-star and ex-boyfriend, Johnny Galecki, who is also dressed up as the Republican presidential hopeful, but with a sombrero.
… We think host LL Cool J's face pretty much sums it up.

Seriously, some things you just have to see to believe.
We have no idea how Cuoco can possibly top that, but we do know that she looks incredible for her performance, rocking nothing but a Calvin Klein bra top and ripped jean shorts.

We think the actress' rock hard abs deserve a prize all on their own!
"I'll see you this Thursday. May the best body win," Gad joked on Instagram on Monday. "And by best, I mean the one least in shape."

Gad and Cuoco's Lip Sync Battle airs Thursday at 10 p.m. ET/PT on Spike.
