EXCLUSIVEThey don't call it the Stanley CUP for nothing -- which is why a bunch of L.A. Kings players used it to serve up champagne to hot chicks in Vegas last night ... and TMZ Sports has the pics. Jarrett Stoll -- along with Drew Doughty and cup-winning goal scorer Alec Martinez -- hit up Beacher's Madhouse at the MGM Grand in Vegas ... and partied with Lord Stanley's hardware until it passed out.
Everyone had a blast -- and they weren't stingy with the trophy ... letting all sorts of people take a sip of the bubbly they kept pouring inside it.
Even Paris Hilton showed up to the party -- though it's unclear if she took a swig.
Stanley Cup -- it's probably hung over right now.
