Before his SNL
hosting debut, Mars had precisely one acting credit to his name: playing a pint-sized Elvis impersonator in the 1992 film Honeymoon in Vegas
. And while most of the episode cast Mars in singing roles which he executed predictably well the hitmaker also proved adept at music-free comedy; for proof, just watch Mars as one of the creepy animatronic Merryville brothers
or as a lonely costumed character in the surprisingly poignant short ''Sad Mouse.''
