I'll tell you what's going on.
This atheist believes Singer's claim as much as he believes in the existence of a bearded Jehovah judging us and consigning us to heaven or hell after we die.
My "interest" in the subject has had one and only one goal: to have the bet go through and to induce Singer for once in his life to back up a brag.
It could be nose size, car size, big toe size: whatever, the point isn't taking the measure of the thing, it is taking the measure of the man.
But without Boz participating this is turning into the typical clusterfuck: sorry I wasted my time in trying to further truth, justice, and the Amercian Way.
