"This room looks like a bomb hit it!"

"Close. I had a thesis."
"I fail to see the similarity."

"You've obviously never done a thesis."

(Got the reports on my thesis back. Basically, they said I was brilliant, but my basic structure and organisation was not as good as it could be. As is so frequently the case, I could have told them this from the beginning. Why did I have to suffer through the damn thesis just to be told that? But there were lots of other lovely and thought-provoking comments, so it's all good, I guess.)
