The two cohosted a post-Emmys Losers Party at Soho House. Nominees who failed to take home a statuette were allowed in for free, but winners had to make a $1,000 donation to World Wide Orphans (WWO).
More than $30,000 was raised for WWO with donations from both winners and losers.
Party-goers sipped on Johnnie Walker Platinum. Those who gave donations were given personally engraved bottles of Johnnie Walker Blue.
Packing into the members-only club were Tina Fey, Aziz Ansari, John Slattery, Elisabeth Moss, Adam Scott, Aubrey Plaza, Poehler's boyfriend Nick Kroll, Jane Krakowski, Seth Meyers, Casey Wilson, Robin Wright and Paul Scheer.
"We figured that the winners get celebrated enough so we thought it was about time that the losers get celebrated," Hamm exclusively told E! News on Friday at Vanity Fair and Maybelline's Mad Men party. "And Poehler and I are friends from a long time ago and every year when we would lose the Emmy we would kind of wink at each other and call each other loser for the rest of the night."
The idea was hatched when Kristen Wiig threw a big bash after last year's Emmys at her hotel.
"We called it the Losers Lounge because nobody that was there won and it kind of stuck," Hamm said. "We were like, ‘That was a really fun party. We should do that again, but we should do it bigger and better and invite our friends who aren't going to win either and we'll have a good time with it.'"
