Yvonne is training a bit in her dojo when this guy comes in on his socks. He says he wants to train but not with a woman. What?! Yvonne thinks he is just afraid - and that is exactly what the Dutch expression " a hero on socks" means :-) Yvonne will show him that she's got more balls then he will ever have - they're just in a different place, and worth looking at :-) When he is almost choked out between her legs he finally starts realizing that he is lucky that she is so mild on him just because he is a such a beginner.
