Just putting this out there: If you ever hear the voices of Neil Patrick Harris and Joe Jonas inside your head telling you to do things, you should proably seek medical attention immediately.

Unless you're Britney Spears doing a bit for "Best Time Ever," in which case you should roll with it and do absolutely everything they say, because you're making television and it's going to be hilarious.

The pop star was a special guest on this week's (Sept. 22) episode of NPH's variety show, where she had some fun with a few unsuspecting dudes who were applying for a position as her bodyguard.

Britney wore an earpiece through which Neil and Joe Jonas (a.k.a. Neil's "second favorite" Jonas brother) instructed her what to say and do, starting with greeting the applicants ("It's Britney, bitch!"), and ending with a surprise physical challenge... which one of the guys was actually pretty good at, tbh. She should definitely hire him when this is all over.
