With most vehicles it take about ten miles or ten minutes to get the exhaust system up to temp, to burn off all of the gases and moisture when you shut down. Watch some other vehicles some time and see them start their cars and let them idle for a minute and the condensation (water) will drip out of the rear tail pipe.
What you are seeing is normal condensation following a short run , that didn't warm up the whole exhaust system enough to expell it as a gas/steam.
As a side note that ten mile or ten minute rule also applies to recharging the battery after a start.

It has a drain hole somewhere. Most all modern mufflers do. As mentioned in a couple of the serious answers, condensation builds up in the exhaust. It needs somewhere to go. If you get under it, I can almost promise you that you'll find a very small hole in the muffler. It's a factory drain.

I love the humor! This always concerns a lot of people but there is a very clear reason why it occurs. First when the exhaust is cold and started the exhaust stream hits the catalytic converter where it is brought back closer to the base elements we have in air. Oxygen, nitrogen and some H2O. What you are seeing is the H2O that is visible until the exhaust warms enough and then it is steam. You will notice on a cold morning cars spewing steam from the tailpipe until the exhuast gets completely warmed up. Then it fades away and becomes invisible to the eye.
Do not worry about it as it is in all modern vehicles that run on gasolene. Or at least more previlent on Gas that Diesel engines.
