So here's Stefan with that evil smile on his face getting these good, older folks rapping dirty English words to the song. Classic Raab, impish, funny and yet a bit mean spirited at the same time. I looked in the background of the seated patrons and there was Heino, standing and looking NOT amused. I'm sure he knew exactly what Raab was up to, and at Heino's expense, LOL.
