I laughed until I cried watching Despicable Me. And then started writing fic. '5 conversations Gru never thought he'd have'.

-I think the main reason they didn't use the anti-grav potion is because there's no antidote to it, and no sign it wears off. Sure, they could have used it, but then they would have been stuck like that.
And there was no sign that it worked on mechanical stuff. Worked well on the Minions though. XD
