Britney Spears is good at taking instructions and she proved it in "Best Time Ever with Neil Patrick Harris" segment of "Voices in Your Head". Neil Patrick Harris and Joe Jonas stayed behind the scene while the pop star repeat their words to prank several bodyguard candidates.

Andrew Opal was the first to arrive and Spears was told to introduce herself by saying, "Hi, I'm the one and only Britney Spears." The second candidate Keith Manning got a "Hi! It's Britney, b***h!" introduction while third candidate Wesley Patterson saw Spears' juggling skill upon entering the door.

When asked why Spears should hire him, Patterson said, "I've worked in the worst security situations." Jonas told Spears to ask, "So, you're like a superhero?" Spears later tested Opal's ability in finding a dangerous object among the audience seats. The pop princess herself had no idea about what was hidden, Harris revealed to Jonas. Then Opal found a cactus pot.

The next test would be to protect Spears while she was dancing on stage. Patterson had the best reaction when she asked him to be "close to me at all times without anyone noticing". He attempted to blend in with the dancers around Spears by making some moves himself. Manning, who was also put on the same test, told the singer "You're full of surprises, you know that?"

"Best Time Ever" airs every Tuesday at 8 P.M. on NBC.
