I think that's what they did. They just chose different words.
I think this story has the elements of humor. Laughing at the overtly pious has always been funny, IMO.
I wonder how they would have reacted if Tim, or some other test taker suggested they sing the Flintstones song before the test was given. That would be fun, too. It would also be irrelevant.
Would those who question the response to Tebow's suggestion be as adamant in their criticism if Tim, or another test-taker, said "Let's praise Satan" before the test" Or maybe if he said, "Praise Allah!"
As far as I'm concerned, he can say "Yabba Dabba Do!" before the test, and it's fine with me. If he asks me and others to do it, I might take issue with his suggestion.
