    Doctor: So, which one of you is Rod Munch?

    Butt-Head: [Points to Beavis] Uhh, he is. He's "Rod".

    Doctor: So, Rod, I understand you were bit by a dog. Well, don't be scared, cause look, a dog bit my thumb off once too, Rod. [He does the old "thumb removal" trick.]

    Butt-Head: You're stupid!

    Doctor: Now, Rod, I don't suppose you brought the animal with you?

    Butt-Head: He wasn't very friendly.

    Beavis: Yeah, he doesn't like me.

    Doctor: Well, we'll have to find him anyway. In a suspected case of rabies, the animal has to be destroyed, of course. And to check for presence of the disease, we cut off the head and dissect the brain.

    Butt-Head: Whoa! That's cool!

    Doctor: Actually, yes! It is kinda cool.

    Beavis: Yeah! Come on, Butt-Head! Let's go find that dog!

    Doctor: Not so fast, Rod. Let's talk about your symptoms, first. Any dizzyness, fever, or any convulsions?

    Beavis: Umm, yes. No more than usual, though.

    Doctor: Hmmm, so far, nothing checks out. Maybe you were lucky?

    Butt-Head: You mean, like, no decrapitation?

    Beavis: [He sneaks another alka-seltzer in his mouth to make foam erupt from his mouth.] I GOT IT! I GOT RABIES!! [He starts freaking out, spitting foam everywhere.]

    Doctor: Ok. I'll call the police about the dog, but first, we better start treatment. [He goes to put on surgical gloves.]
