Remember those Chinese sketches in which a nurse gets caked by a doctor? (discussed e.g. here: https://umd.net/forums/chinese-caking-videos-found-on-ixigua ).

It seems those were originally inspired by 2 Saturday Night Live Korea sketches called "Surgeon Bongdari".
In the 1st one from S4E17 (15 June 2013), actress Kim Seul-gi gets caked:

and 2nd following one from S4E18 (22 June 2013), Seo Yu-ri gets caked:

Both follow the same plot, the doctor is played by the same guy (Lee Beom-soo), just different actresses get caked

Wow, amazing research!

First one is great. Not crazy about the second one because of her wig (though I guess we can't really blame her if it's a live show and she has to do other skits after). Although on the second one the caking was so hard that a bit of it hit the woman coming in behind too!
