How I Met Your Mother Season 6 Episode 9 (11/15/10)
Thanks, Barney! Because this character finds a copy of the Canadian show "Space Teens," viewers enjoyed more of Robin's alter-ego this week. It had been too long since we'd seen "Robin Sparkles," hadn't it?
Also, Nicole Scherzinger guest starred as "Jessica Glitter" and Alan Thicke also made an appearance.
