If you've ever been so nervous about meeting a VIP that you did a series of mental flails and then just straight-up crammed your figurative foot into your literal mouth, then you'll be relieved to hear that you're not alone: Charlize Theron knows that feel.

The "Mad Max" actress was on "Jimmy Kimmel Live" last night (July 20), where she told a story about the terrible, humiliating thing that happened to her the last time she was on the show, when she just happened to be backstage at the same time as President Barack Obama.

We don't want to spoil anything, here, but let's just say it starts with Charlize being nervous about meeting such an important public figure, and ends with her lying awake in the middle of every night for the rest of her life remembering the time she invited the President of the United States to a nudie bar.
