Here's a funny story just for you:
I was watching Flight of the Conchords Wednesday evening, which is a hilarious show on HBO. It was so hilarious that I fell asleep. The next morning I woke up at about 7:30 and realized my alarm hadn't gone off, so I got up and started getting ready for school. I relieved my aching bladder and as I was getting in the shower I was trying to remember what I did last night:

hmmm...did I go to Bob and Josh's? no, Josh was getting off late. did I study for the quiz tomorrow? shoot, I didn't. I gotta review those key terms before class. why did I sleep on the living room couch last night? I never sleep on that couch. why didn't I at least go hang out with Bob? he didn't work tonight. I wonder if he called me.
I grabbed my phone.
no, no missed calls or texts, that's weird.

WAIT.

It's 7:40 PM!

I then began to laugh at myself. And got out of the shower.
