This sounds like the story doing the rounds in South Africa. It is probably an urban (or bush) legend, as the names and places allways seem to change.
It is about a couple of guys who hire a Combi to go on a hunting trip. On the way there they start the party and imbibe a few alcoholic beverages. The farm was a long way off, so the few became many. It also became night time. Kudu are fond of jumping into cars at night, but our friends are not concerned. However, the inevitable happens and they knock this kudu bull down, luckily without to much damage to Combi and person. So these guys, very clever by now, decide that the hunt may as well start now and proceed to load the kudu into the combi. About 15 min later this kudu comes to life. It was only knocked out cold. So it thrashes about, the side door flies open and everybody in the back bales out of the still moving vehicle. Dusty, scratched and with torn clothing they run after the vehicle, which has now stopped. The kudu has in the meanwhile stood up and shoved its horns through the roof and was stuck. In this chaos someone managed to get a rifle and shot the kudu through the open door. needless to say the bullet went through the kudu, spraying blood all over the show, and exited through the side panel.
Not perturbed everybody got back in and continued. This hunt was going to be fun!!
When they got to the farm, the farm owner took one look at these drunk, bloody, dishevelled bunch, with a stuffed combi and send them packing!!!
