pulling a mitchell

When you do a project for a foreign language class the morning it is due and don't prepare the speaking part at all but still get an A on it.

I pulled a mitchell on that French project that I presented today. I can't believe it worked!

How often do you pull a Mitchell?

I swear, pulling a Mitchell works every time for me. It's a lot better than doing it a few days before hand.... Preparation for weaks!
