Lol. You can totally tell they were
almost starting to laugh at the end. Rupert looked like he was about to crack up XD Ahh, I love the trio.
Edit: LOL! I can't stop watching this video. It's so funny how they're almost going to laugh

Look at Rupert when he says "2,000". Then rewind back and look at Dan and Emma when Rupert says that. Bahahhaa
