How I Met Your Mother Season 6 Episode 2: Cleaning house

Barney's mom, Loreta is about to sell Barney's childhood home. So Barney asked the gang or should I somehow convinced them in helping him pack his things. Barney's black brother, James is also helping out. As they were packing, they discovered a envelope addressed to a certain Sam Gibbs with their photo of the two of them in it with "Your son" written on the back. Barney is afraid of the possibility that his biological father is Sam Gibbs but James eventually convince him to go.

When they confronted Loreta, she refused to answer their question. So they decided to visit Sam. Before they met him, Barney confess that he knows that Bob Barker is not his father but since he has confidence issues while growing up, he thought that having a celebrity father makes him feel special.

They discovered they Sam was an African American which obviously James' biological father. Then Barney thought that he was meeting his father. He cracked and pretended that he was Sam's son as well. Barney somehow had a theory that the reason why he so good in basketball is because he was black. Loreta told Barney when he was young that he was not picked in the basketball team because he was simply so good that it would be unfair to the other kids. But in reality Barney sucks in basketball.

Loreta told Barney that Sam is not his father and  realize that much of his childhood were filled with lies. Loreta offered to tell him who his real rather is but Barney refused. The highlight of the episode for me is when Barney was butting in with Sam and James' duet. I especially like the part when Barney used a voice box to ruin Sam and James "Stand by me Duet".
