"Belly Full of Turkey" -- When Ted and Robin give thanks by volunteering at a homeless shelter on Thanksgiving Day, they are shocked when they see the last person they would ever expect doing good for others, on HOW I MET YOUR MOTHER, Monday, Nov. 21 (8:30-9:00 PM, ET/PT) on the CBS Television Network. Pamela Fryman, one of the series' executive producers, directed the episode written by Christopher Miller and Phil Lord.

When Ted and Robin decide to help feed the homeless on Thanksgiving Day, they are in a state of disbelief when they run into Barney and discover that he is a regular volunteer at the homeless shelter. Thanksgiving doesn't end there for the trio, for they end up somewhere that only the "real" Barney would bring anyone to for a holiday meal. Meanwhile, things do not go very smoothly when Marshall and Lily pay a holiday visit to Marshall's family in Minnesota.
