How I Met Your Mother

Barney is dating Robin.

Ted is a professor that formerly crushed on Robin.

Therefore, on an upcoming episode of How I Met Your Mother, it's only natural for Barney to seek words of wisdom about his girlfriend from his pal.

“There’s a show coming up called Robin 101 where Barney seeks Professor Ted’s advice to learn more about Robin’s likes and dislikes to gain a deeper knowledge of her," Neil Patrick Harris said to TV Guide Magazine. "Ted, of course, knows all about Robin because he was kind of obsessed with her, whereas Barney just likes to stick things in places.”

Sorry... he likes to what?!?

On the next new episode of How I Met Your Mother, viewers will see a sexy side of Lily. Kind of.
