During Adam's best prank yet, the Voice judges and audiences sat back and watched on Monday's show, as a video from a camera stationed outside of the studio showed two yellow bulldozers dumping piles of manure right on Blake's bright red truck.
"I thought I would return the favor, why not pay him back a bit," Adam said with a smile, as Blake shook his head. "That is cow dung, that is feces of animals."
"That's going to be a bad ride home for you tonight," host Carson Daly teased. "Shut up!," Shelton said as the crowd erupted in laughter.
The duo is notorious for teasing and pulling pranks on each other. When Adam dyed his hair platinum blonde, for example, Blake called him Miley Cyrus and "the sexiest woman alive."
Just weeks ago, Blake posted the Maroon 5 front man's private phone number on Twitter, writing, "@adamlevine... I just found the craziest thing in my phone!!! Your PERSONAL cell phone number... hope I'm not stupid enough to tweet it out..."
".@blakeshelton your threats are so cute," Adam responded, with Blake quickly tweeting, "HEY EVERYONE!!! Here it is: @adamlevine's CELL NUMBER! Think I'm kidding? Try calling it!! B––––!!!"
This was definitely real. Adam's phone started blowing up immediately after the post, and he had to disconnect it.
