If you've ever run into a celebrity or well-known figure, you'll know how tongue-tied the experience can leave you. There's just so much pressure to say or do something funny or impressive, just so you can walk away with the belief that you've influenced their life in some meaningful way - even if it's only for a minute. Unfortunately, because these run-ins usually happen at such short notice, you very rarely have the chance to even gather your thoughts, let alone say something witty. So, of course, you end up blurting out something stupid, and the experience periodically comes back to haunt you for the rest of your life - usually when it's about three in the morning and you can't sleep. Don't know what I'm talking about? Well, these 14 people certainly do... 1. I'm sure she loves you too 2. Should've said yes 3. At least she was nice 4. It's a secret 5. Who could be disappointed with Jonah Hill? 6. Not the best first impression 7. I'd probably panic if I met <a href="http://vt.co/entertainment/celebrity/1-sophie-turner-joe-jonas-announce-engagement-instagram/">Sophie Turner</a>, too 8. The angle could have been slightly better 9. That could've ended badly 10. Ever the gentleman 11. I don't blame her 12. It's certainly an original question 13. Well, it's true at least 14. Wait, that's not his name? So, if you ever find yourself running into a famous person in the street, maybe just stick to a simple "hello, it's great to meet you". Oh, and be prepared to take a decent selfie.
