Pascals wager?

uming Blaise Pascal was a moderately intelligent man how could even entertain for a moment such a flawed proposition. Refuted by no less a theologion than the great Homer J. Simson (What if we choose the wrong God, then every time we pray we're just making God madder). It's not a either/or argument even in Pascal's time there were a multitude of religions each threatening their opponents with eternal damnation. So, am I missing something?
