My Step-by-Step Guide to a Day in Paris

1) Book a flight with a 12 hour layover in Paris.
2) Have a friend coincidentally have the same flight to Paris, but with only a 4 hour layover.
3) Get the idea in said friend's head that 4 hours might possibly be enough time to maybe go into the city, see the Eiffel Tower, and get back to the airport in time.
4) Leave the friend alone during the flight to allow him or her to develop this idea on his or her own.
5) Upon arrival in Paris, don't say anything that suggests you truly think it's a crazy idea.
6) Spend an hour wandering around the terminal searching for the bus that supposedly goes to somewhere a short distance from the Eiffel Tower.
7) Fail to find the bus, and get on another bus instead. Bus ride should take longer than expected.
8) Enjoy your friend's company on the bus despite the friend starting to freak out that this was a bad idea.
9) Get off at the Opera House.
10) Get yelled at by a French guy in his car who claims you interrupted his friends to have them take your picture.
11) Say farewell to your friend as they get back on the bus a total of ten minutes later to go back to the airport.
12) Spend the day wandering around Paris, in and around museums, checking out all the highly inappropriate artwork that the city has to offer. Take pictures of your favorite stuffed animal in compromising positions with the statues.
13) Eat at a restaurant that makes their own pasta and tomato sauce.
14) Walk the long way to the Eiffel Tower because you'd think it would stick up over the skyline and we easy to walk towards. You will be very wrong about this.
15) After going up the Eiffel Tower take a cab to the Arc de Triumphe where the bus you planned on taking from the airport supposedly has a spot. Spend ten minutes wandering around looking for it and getting absolutely no help from the generally unfriendly French policemen and other locals.
16) Get in yet another cab to get back to the Opera House.
17) Arrive at the gate 5 minutes before boarding.
18) Pass out on the plane from being on your feet for 12 hours straight.
