My sis linked you to a lot of the funny moments up the thread...
but she managed to leave out a lot.
=P
I went up to Silent Bob and asked 'Are you really silent?' his response was 'What?' followed by 'Oh, rats.'
I piggybacked another Naruto, it was cloneyback, or something... the funniest thing was everyone's reactions. Lots of stares and laughs and photos XD
Going to the Merlin panel. Total shocker there... I don't know if you heard, but the first question (on their first ever outing and panel) came from Curse Mark Two Sasuke and was 'Is Merlin a gay(yaoi!) love story?' LOL!
When Kakashi came and sat unwittingly between three Narutos. (Three Narutos hanging out together was a bit weird aparently, people kept photographing us, and Tobi and Deidara came and sat with us and Sakura- major lol) Anyway, Kakashi sat with us. I'll let you know we didn't plan what we did next... we just did it. It's that bedarned clone mental link.

We still didn't get the mask off!!!
And one really funny thing. I mean it was a bit terrible at the time XD but so ironic...
Our team 7 group + extra (Naruto, Sakura, Sasuke and Vincent) went out to eat after expo, but on the way back to the docklands Sasuke got on a tube before the rest of us and... well, the train left, and we lost Sasuke XD so there was a Naruto, Sakura, and Vincent running around several stations trying to find Sasuke.
