Yes, German Soccer Coach Joachim "Jogi" Low ate boogers while watching/coaching his team in the World Cup. Yes, that is absolutely disgusting.
But it's not his fault.
I blame his mother. Everyone knows that one of the most sacred responsibilities of a mother is to yell "Oh yuck! Don't do that!" when a child picks their nose. And her responsibility is to times that reaction by 150 thousand if the booger retrieved from the nose is aimed towards the mouth.
Joachim clearly didn't have a mother who did that. That's the real tragedy.
