Jesus in a hat

Erik has a Rembrandt painting as his desktop, and it depicts Jesus in a hat. What the heck? And he has a shovel in one hand. So I googled "Jesus in a hat" and got eight hits. One is talking about a different painting depicting Jesus in a hat--in that painting, his upper body is naked and the shovel is in his left hand, but in Erik's Rembrandt, the shovel is in his right.

Anyway, I said "Jesus in a hat" would be a good curse, but we decided it doesn't roll off the tongue. However, my high school band director would curse "God bless America."
