Irony: Part N

I suppose I ought to appreciate the irony of several birds dive-bombing me while I am marking ballistics problems on my students' dynamics homework.

(But, really, I am annoyed that I now need to wash my jacket and take a bath. The first bird already forced that, but after the second and the positive feedback loop that might be occurring, I just needed to escape inside.)

I ought to design a homework problem based on this, though...
