Saget took to Twitter to say the show – which turned out to be his last – was a success. 

"I had no idea I did a 2 hr set tonight. I'm happily addicted again to this sh*t," he wrote.

"I'm back in comedy like I was when I was 26. I guess I'm finding my new voice and loving every moment of it. A'ight, see you in two weeks Jan. 28 & 29. And check BobSaget.com for my dates in 2022. Goin' everywhere until I get the special shot. And then probably keep going cause I'm addicted to this sh*t. Peace out," he wrote.

The tour was supposed to continue until May. 

Saget has featured in a host of television shows over the years, starring in Quantum Leap, Entourage, Law & Order, Fuller House, and was the narrator for Ted Mosby on the CBS sitcom How I Met Your Mother from 2005 to 2014. 

In his personal life, Saget was married to Chicago journalist Kelly Rizzo in 2018. 

The 42-year-old reporter previously poked fun at how they met during a TikTok video, admitting he "slid" into her DMs on Instagram a few years ago. 

"I think Bob was looking for a good Midwestern gal, a Chicago gal, like myself. So, he saw my Instagram and he's like, 'Oh, it's not all selfies and bikinis, like she actually does stuff. She has this food show and travel show. She seems interesting'," Rizzo said last year. 

"He said, 'Hey, want to come to a show of mine and then go out for some burgers and lobsters. And then I was like, 'Okay, we could be friends'. 

"And then I was like, 'Oh no, I kind of like him.' And then we got married. And now it's been five years, and, yes, our house is very clean. And, no, being married to a comedian does not mean everything is always funny." 

Saget has three adult children with his first wife, Sherri Kramer, whom he was married to for 15 years before their divorce in 1997.
