I was in New Zealand, was going to a beach party with some girls from the hostel I was staying at. To get to the party, you needed to take a $2 ferry across this inlet which was about 1km wide. I decided to swim it, to impress the ladies.
About halfway through I realize that I'm slowly being swept out to sea and I'm losing strength. I'm not sure how, but eventually I made it to the other shore, about 100 meters away from the pier. The ferry had docked about 2-3 minutes before me, and I just nonchalantly walked over to meet the girls, as if I hadn't swum against a current to near exhaustion and was swept out to sea.
Good side: it worked and I ended up hooking up with one of the ladies
Bad side: the $2 was for a round trip, and I still had to pay $2 to get back once the party was over
