LOL. OH, I love how Severus is blaming the twins' shenanigans on everybody else. It's not that he might have left his lab's door open, no. And never mind the fact that these kids sound pretty much like a right mix of Harry's mischievous nature with a healthy dollop of his own slytherin cunning, that has to be poor George's fault... Hummm... I wonder how long he'll keep on holding on to that excuse... :D

Lovely scene, my friend. Perfect for the prompt at hand. :)
