"Single Stamina" is the tenth episode in the second season of the television series How I Met Your Mother.
[2] It is winter in New York City; Marshall, Lily, Ted, and Robin are in "couples' hibernation mode".
Tired of being his own wingman, Barney announces that he's invited his brother James (Wayne Brady) to town.
He has been turning down a lot of guys tonight, complaining about his feet hurting him, and generally acting like the four of them.
Marshall and Lily leave because of the time but Ted and Robin stay (hinting at the fact that they have broken up at this point, as they both have "single stamina").
Barney meets James's son, and promises to take him out on his 21st birthday and show him how to pick up women.
