Who is "Gusto?"

As you may know, I have a propensity for nicknames. A lot of them.  Even now for Paco's friends in the 4th grade.

They are Chuckdog, Vito, Frankie, Tony, Hunter, and Stefan. And believe me...those are a long way from those kids' actual names ;-)

Anyway...the other day, I saw Paco in the youth groups at our synagogue through the window.  He was actively participating.

As I reported back to the NFO at lunchtime, with Paco present, "yes, he was in groups. He was praying with gusto."

To which Paco (aka Jokinen) said: "who's Gusto?"
