Man gets served and hi-fives his friends

So I'm serving in Delaware County a few nights ago. I go up to this house. There are like 5 guys standing outside drinking beer. I introduce myself and tell them I am there to serve such and such. The guy I'm looking for steps and admits that's him. I serve him the summons. His eyes light up like its Christmas morning. He turns around to his friends and gives them all high fives! I've served nearly 40,000 papers and that reaction is a first.
