I desparately wanted a blowjob from my girlfriend, but she said she had a headache, so I put powdered aspirin on my dick just to prove that I really needed her to release the building pressure in my balls.
The painful headache you get when you are working on math for too long. Usually occurs while cramming before a test, making up half a semester's worth the homework or can also occur while completing a BYU online math course.
I've beenworking on the BYU course now for three hours straight. What has algebra done for me besides give me a massive math headache?
