'SNL' co-stars Kenan Thompson, Taran Killam go bowling together

"SNL" boys night out!

Co-stars Kenan Thompson and Taran Killam spent Sunday night bowling and watching football at Frames Bowling Lounge in midtown.

Even though it was just the two of them, the funny guys rented out the entire VIP lounge, a source told us.

"They were totally low-key," the source said.
