What do you say we go out Saturday night?

What?

Hello?

Hey, yeah, Steph! This is Dave from History class.

Oh, Dave.

Hey, I was wondering what are you doing this weekend?

Dave, I was just diagnosed with H1N1.

I got a headache.

My stomach's acting up.

If this fails, use step two.

Oh, Saturday I have to take my brother to the gynecologist.

Fake someone else's illness.
