Pontchartrain Puns

I was on a very nice boat party with my friend, his father and a group of their high class friends. We were in lake Pontchartrain in New Orleans, and one of the elitist sailors was trying to determine if I was seaworthy and see if I even knew where I was.

I said "Sure thing", started pointing left "over there is the port of New Orleans", now pointing to the right "and over here is the starboard of New Orleans".

My friend's dad heard the joke, and while laughing a bit he told me "One more bad joke and I'm kicking you off". To which I replied, "You're right, I should have let the opportunity sail away."
