List your favourite Glee Logic moments (possible spoilers for the uninitiated.)

They come up every episode and I thought it'd be cool if we shared some of our favorite moments of Giving the questioning head tilt.

To start off: every moment with Terri. School nurse? Not getting arrested for drugging students? Assistant manager who only works a 12 hour shift and doesn't expect to do any work? Gets away with faking a pregnancy (almost)? And this is just from the first half of season one.

So, what are your favorite moments of Glee logic?
