Drive the dentist out into the bush. After finding a pride of lions, push him out of the vehicle and drive off. Return the next day to pick up the skeleton—if the lions will allow that.
You would have fit in just fine in ancient Rome.
Puleez, this guy was an dumbass for sure with more money than sense and very poor judgement without a doubt but death by being fed to lions, really? I don’t think so. Isn’t that what Saddam & his sons use to do to people during their reign in Iraq?
