Customers at a CVS drug store got a little bit of a surprise when 50 ducks waddled through the automatic doors. So, what do you do when something like this happens? Whatever you do, don't quack up! Sorry, I couldn't resist.

According to MSN Now, CVS employees and customers in Saratoga Springs, N.Y. got quite a shock when the ducks made their entrance. After everyone looked around probably thinking to themselves, "Um, is that a bunch of ducks I'm seeing, or am I losing it," a worker ended up luring the ducks out with a bag of popcorn.

No damage was reported except for about 50 pairs of little webbed mud marks on the carpet.

Of course, someone was able to whip out their smartphone and capture this weird duck invasion. Watch the video below.
