Get a Free Pretzel on National Pretzel Day

The Philly Pretzel Factory said it hands out free pretzels to every customer in their 100 shops as it is "National Pretzel Day" Tuesday.

The celebration got its start in 1983 when Congress introduced the holiday.

Also part of the celebration will be a National Dance Week with a Pretzel Twist dance invented by "So You Think You Can Dance" finalist Alex Wong.
