Blake Shelton appeared on 'The Tonight Show' with Jay Leno on Wednesday (Feb. 5), and as always, the singer showed everyone why he's one of country music's funniest guys. His time with Leno included stories about getting high, his beautiful wife Miranda Lambert and drunk tweeting -- just to name a few.

Shelton sat down on the infamous couch next to actress Sandra Bullock, who had just choked up as she told Leno how much he means to her and the entertainment industry. The 'Boys 'Round Here' hitmaker didn't cry, but he did draw lots of laughs right from the start.

The talk show host asked Shelton about his performance with Willie Nelson, Kris Kristofferson and Merle Haggard at the the 2014 Grammys, specifically wondering if it was nerve-wracking to deliver in front of his peers. Immediately, the country star responded, "I was high."

He delved into the back story, explaining, "Backstage, I was sharing a dressing room with Willie and Kris Kristofferson and Merle Haggard and my wife, Miranda."

Instead of letting Shelton continue, Leno interjected, "Your wife was in there, so did she change in front of all those guys? You shared the dressing room with your wife and Willie and all these guys?"

The singer hilariously called him out, exclaiming, "I'm trying to tell a story about marijuana and you wanna see if my wife's naked in the dressing room?"

It was a segment full of funny moments, which included Leno reading off Shelton's tweets. "A lot of people know you drunk tweet," he explained. "These are actual Blake Shelton tweets. I want to know if you were drunk or sober at the time you said this."

Not surprisingly, Shelton couldn't remember writing a lot of the messages on the social media site.

At the end of his time on 'The Tonight Show,' the country hitmaker presented Leno with a goodbye  gift -- and let's just say that Shelton added to the comedian's seemingly never-ending supply of chambray shirts and jeans.

Thursday (Feb. 6) was Leno's final run on 'The Tonight Show.' He was joined in his farewell by country music legend Garth Brooks, who played him out of his 22-year run with 'The Dance' and 'Friends in Low Places.'
