Well, the first ride in it from the bar to the hospital, at least. You don't actually get to keep the ambulance.
Still, as a person who's been to the emergency department due to a knife boo-boo, I can tell you, you'll love that the doctor will ask you to repeat your story several times (to make sure you weren't attacked or doing something illegal):
"We were fine. We had put our ER's away and broke out some small fixed-blades in 1095 to see if the tequila and lime that Thom and Allen puked onto the bar would make a unique patina on our blades. Really, I should know better than to smear CrO rouge on my shirt to strop away surface corrosion, but Jaeger is a tough Meister and well, that's why none of us have fingers.... ...Except for Frank. He nursed a Sambuca Molinari and wouldn't touch cutlery if it wasn't N690."
