For Davidson, the 8-minute cameo marked a rare public outing as he's temporarily stepped out of the spotlight.

Before SNL, he was most recently seen out alongside pal Machine Gun Kelly Oct. 23 in Los Angeles, where he debuted the progress of his jaw-dropping tattoo removal, a stark difference from his previous appearance in which his arms were filled with ink.

So why is he cleaning up his look? Well, now that he's pursuing a career in acting, he wants to avoid sitting for three hours getting his tattoos covered up.

As he explained, "For some reason, people in movies, they don't have them that much."
