Bill Hader is dusting off that tattoo-print shirt and channeling his inner club kid as he returns to Saturday Night Live to host the show that launched his career.

The 36-year-old funnyman, who brought the LOLs during his eight-year run with characters including Stefon, talk show host Vinny Vedecci, and Dateline correspondent Keith Morrison, is hosting the Oct. 11 show and Yahoo TV caught up with him as he arrived back at Studio 8H on Monday to prep for his big gig — and goof off former castmate Kenan Thompson.

"It's really nice to be asked to come back to host. It's very sweet," the Skeleton Twins star said in a brief serious minute during our interview on the set. Then, with prompting from Kenan, 36, he pretended to read a prepared statement written on his hand, "Oh, yeah — [it's a] dream come true. One of the biggest moments of my life."

Kenan was more sentimental. "It's exciting. He's my bro," he proudly said of Hader, who left the show in 2013. "I think it's awesome that he's done so well in life that he gets to come back and host."

While it seems like a sure thing that viewers will get to see Stefon again (the flamboyant "Weekend Update" correspondent, who married Seth Meyers on the show, is Hader's most famous counterpart), he also revealed the one character he always wanted to play, but his pitch just kept getting shot down in the writers' room.

"I was a guy on a college campus that was clearly in his 60s from Santa Fe and I was trying to talk college kids into coming to Santa Fe for spring break," Hader said, breaking into a silly-voiced impression. "'How about we go to Santa Fe?'"

Before he even finished, Kenan shook his head at his old friend, laughed, and quipped, "Nobody wanted to go to Santa Fe."
