A Coast Guard father deployed overseas for the past seven months dressed up as a school mascot to surprise his daughter at her Maryland middle school last month.

The father -- disguised as the Stephen Decatur Middle School bulldog -- is seen in a now-viral video walking through the cafeteria before approaching his daughter, Madi.

Madi even extends her hand out for a high-five to the mascot while eating lunch with her friends, before her father removes the costume's headpiece to give her the surprise of a lifetime.
