09E10 - Mom and Dad

Barney gives Ted, his best man, a gift for Robin to hold on to. That gift, a signed photograph of Wayne Gretzky, is ruined while in Ted's possession. Ted is certain he was sabotaged, but by who and for what reason he isn't sure. Ted the detective goes on a quest to find the perpetrator, which isn't an easy task as Lily keeps reminding him that he has never been very good at deduction. Meanwhile, both Barney and James' biological fathers, Jerry and Sam, are in attendance for the wedding - Sam who will now be performing the wedding ceremony - which will be the first time in a while that Loretta will have seen these two of her ex-lovers. Both Barney and James have had fantasies of their respective father and Loretta getting back together so that they can be a traditional nuclear family, which adds a strain between the brothers. But Loretta, Jerry, and Sam may have some say in Barney and James' fantasies coming true. And after Marshall and Daphne seem to be getting along, Daphne all of a sudden turns on him. Marshall tries to figure out what went wrong and what he can do to make whatever he did up to Daphne.
