That 70's migraine
Follow my logic. I have been coming down with migraines at night.
"That 70's Show" is on in syndication on our local WB at 6:30, and then on at various times during prime time on Fox.
Whenever I have a migraine, I find myself watching "That 70's Show."
Therefore, "That 70's Show" is responsible for my migraines.
That's the only explaination!

I've given it a little more thought and I think it's not "That 70's Show" as a whole. It's just Ashton Kutcher.
