The gang learns a new exciting (but poorly aged) way to initiate an intimate relationship with a date. Lily completes a list (awesome) of 50 reasons to have sex. Ted gets back out into the dating world.
This bottle episode centers around Barney's deception to convince his mom (we finally meet Loretta) that he is a family man by hiring an actress and actor to play his wife and kids.....the gang gets involved in hilarious ways.
The brilliant follow up to Sorry Bro, we get more Karen; Lily the relationship wrecker; Robin's greatest day at work; Barney and Marshall in nightgowns....errr shirts.
