Sick Dogs Have it bad

I feel bad that when a dog is sick, the vet will check them out by sticking a finger in their butt. Although when I get checks out by my doctor and he has to stick a finger in my butt... i kind of like it.

I might like it too much, because when I go to the doctor with just a fever... sometimes I'll try to get him to check through my butt. Worse still, sometimes he does! Am I the jerk for wanting the butt check or is he the jerk for checking butt when the problem is that I obviously need therapy?

When a dog's butt gets check they just kind of stare at their masters with a kind of "You did this." face.
