Are SNL Writers Ripping Off Skit Ideas?

The legendary show got rave reviews...except for one problem.

Does this sketch from a Los Angeles comedy school look familiar? 

Two actresses in Los Angeles (and many others) think so. They've accused the Saturday Night Live writers of ripping off their material for a sketch on the show this weekend.

In the skit, host Sarah Silverman and cast members Cecily Strong and Sasheer Zamata played Tina Turner impersonators on a Nebraska riverboat.  The three swap sob stories while performing Turner's “Proud Mary.”

Two members of sketch comedy school performed a very similar skit for six weeks this summer. One of the actresses posted on her Facebook page: 

A video of the SNL skit isn't on NBC's website but you can find it on Hulu

A SNL insider who declined to be named said  “It's a common idea since Tina Turner is such an iconic figure. The similarities represent parallel thinking in the comedy world.” 

What do you think? "Parallel comedy thinking" or a real rip-off?
