A Greek and a Scotsman

:A Greek and a Scotsman were sitting in a Starbucks cafe discussing who had the superior culture.
>>
>> Over triple lattes the Greek guy says, "Well we Greeks built the Parthenon" and arched his eyebrows.
>>
>> The Scotsman replies, "Well ... it was the Scots that discovered the Summer and Winter Solstices."
>>
>> The Greek retorts, "We Greeks gave birth to advanced mathematics."
>>
>> The Scotsman, nodding in agreement says, "Scots were the ones who built the first timepieces and calendars."
>>
>> And so on until the Greek comes up with what he thinks will end the discussion. With a flourish of finality he says, "The Greeks were the ones who invented sex!"
>>
>> The Scotsman replies, "Aye, that is true, but it was we Scots who introduced it to the women!"
