If you're ever in San Francisco International Airport and you're stressing about an upcoming flight, it may help to pet a pig.

Yes, and while she may not be a Montana pig with a friendly, want to help attitude like so many Montana people have, she's there if you need her and she's doing a wonderful job.

Her name is Lilou, and she's part of the SFIA's "Wag Brigade," therapy animals that help relieve passengers' stress. Lilou is a huge hit. Passengers love to pet her snout and stroke her back. Of course, they can't get anyone to buy a BLT sandwich on any of the flights anymore, but.....

You can't miss Lilou. She gets to wear a pilot cap and a blue tutu. She's going to need a therapy human after being on the job in that outfit!
