Last night’s SNL featured a hilariously collection of clips of Justin Bieber (Kate McKinnon) showing off his new Calvin Kline underwear, or as he calls them, “clothes for my big wiener.”

Watch as the pop star drinks (juice boxes), combs his (nonexistent) mustache, shows off his ink (“this tattoo made me say ‘owie'”), tries to hump the female model on the set, and does all the other things one would expect now that he’s a self-described “big boy”.

Watch, AFTER THE JUMP…
