Entertainment Tonight had an exclusive first clip last night from Britney Spears’s seemingly therapeutic stint as a guest star on How I Met Your Mother, which resumes Monday night. In it, Barney (Neal Patrick Harris) uses Britney’s obsessive character, Abby, to make his estranged friend Ted “jealous.”

“Girlfriends are lame! Unless they’re me.” It is fun to see Britney “play” crazy.
