My Cool Dentist: “It’s been about 15 minutes. That shot should have you all numb by now.” (starts drilling)
Me: “Uh… I can feel that.”
MCD: “You said you were a little hard to numb. I already used half a cylinder of Novocain. I guess I’ll use the other half.” (poke poke stab)
(10 minutes later)
MCD: “That 2nd shot has had plenty of time to take effect, so we’re ready to drill.” (starts drilling)
Me: “Uh… I can feel that.”
MCD: “Really? Wow. OK. Nancy, get me another tube. This might numb your whole mouth, so just don’t bite your tongue.” (shoots entire 2nd tube into my jaw)
(5 minutes later)
MCD: “OK, can you feel anything now?”
Me: “Aaag cabber ffulizzz aggerrrzheeen.”
MCD: “That’s what I like to hear.” (starts drilling)
Very Vocal Viking 
So next time…horse tranquilizer? Tequila?
The funny thing is… every other form of medicine affects me super hard. Benedryl makes me loopy for days. Tylenol makes me sleepy sometimes. But Novocain… must be a natural Viking immunity. Or perhaps it’s counteracted by pork, which would explain a lot, frankly.
