It IS worse the second time

So the whole video blog thing that Anne and I are indulging in was inspired by an author Anne is familiar with, John Green (An Abundance of Katherines, Looking for Alaska) and his brother Hank. After finding that their relationship was turning almost completely textual, they decided to go for a whole year of textless communication. They are calling it Brotherhood 2.0. I find it highly amusing and recommend you check it out. There is one video blog post a day for each weekday alternating between them. As part of this project if they miss a day or use textual communication there are punishments. Today was the first such occasion as John accidentally cc'd Hank on an email he sent. Seriously, although a bit disturbing in that I find it funny, watching a man find out the joy that is waxing made me laugh out loud.

Question: Why didn't the Yeti warn him to pull the skin taut before pulling?
