Immune at last - plus animal crackers

I just received two immunization shoots this morning in order to be able to register for class. However, now that that's done, all the classes are full! So now it looks like I will not be taking any classes at all over the summer. I hate this waiting list crap.

Now on to animal crackers. The other day in class, where apparently I was a menace to everyone since my immunization records were not up to date, I noticed that when I eat animal crackers I always bite the heads off first. Why is that? I know I have enough psych friends who read this (you read this, right?) and even though they never comment, surely they have something to say about this!
