Am pulling an (almost) all-nighter. How do we know it's an all-nighter (or thereabouts)?

I'm getting out the elastic pants.


ELASTICA SCHOLASTICA IS NOW IN SESSION, FOR THE FIRST TIME SINCE LAST WINTER QUARTER!


Edit: omg omg omg! I'm watching TV instead of studying, and I'm watching this thing about ectopic pregnancies and this one woman had a baby in her for 46 years and it turned to stone/calcium. And they showed the surgery to get it out and it was so gross! Oh my gawd, I cannot even explain how scary it was!
