Why does North America have the most Atheists?

[Brakeman]

Wow I am evidently so poly-religious!

On Sundays I go to atheist "no such thing as gods" church,
on Mondays I go to " no such thing as big foot" church,
on Tuesdays I go to " no such thing as little green aliens" church,
on Wednesdays I go to " no such thing as homeopathy cures" church,
on Thursdays I go to " no such thing as witchcraft magic" church,
on Fridays I go to " no such thing as fate" church,
and on Saturdays I go to the " no such thing as ESP" church.

I guess I have to believe everything else because I've run out of days to worship..
