That's like the two nuns sitting in their car at a set of traffic light when Dracula jumps onto the car bonnet and starts hissing at them and baring his fangs. The younger nun says to the elder one "sister Mary what shall we do"?
Sister Mary says "I'll start to drive off, you show him you're Cross"
So the younger one says "Oi you!!!! get off our fcuking car or I'll punch you"
The vampire then took the drink and its contents to a renowned archaeologist and utterly confounded them when they came out with the question.... .... "So what period do you think this is from then?!"
