A man walks into an antiques store...

A man walks into an antiques store carrying an intricately painted china dish, to find an elderly looking gentlemen behind the counter.
'What can I do for you, sir?' The elderly gentleman says.
'How much would you pay me to take this off my hands' says the man.
After looking at the plate, the gentleman behind the counter and rudely snorts, 'this plate is a counterfit of those made in the Joman Period, I will pay nothing for this'.
With that, the man storms out in silent rage at his rudeness.

The same man enters the same antiques store the next day, this time carrying an intricately designed vase, to find the same elderly looking gentleman behind the counter.

'What would you pay for this, then?' The man says.
After looking at the vase, the antique dealer rudely sneers and exclaims 'Why, nothing sir! This vase is a counterfit of those made in the Coptic Period, I would never buy such a disgrace!'.
Again, with that the man storms out in a silent rage at his rudeness.

The same man enters the same antiques store for the third day running, this time carrying something concealed in a bag, to find the same elderly gentleman behind the counter.

'Ah, the counterfit king returns. What is it this time?' The elderly antiques dearly teases, nose upturned pretentiously.
Staring directly into the arrogant antiques dealer's eyes, the man reaches slowly into the bag and removes a used tampon from the bag and slaps it down on the counter.
'There you go, you clever bastard. Tell me what period thats from'
