LOL... at the local watering hole that I frequent, there's a guy like this. Just DAMN. Makes yer eyes bleed. It's so intense that it really seems impossible that such a gas could come from anything that is still alive.
Which is nothing compared to what happens when he heads for the bathroom. Dear Lord. He's been known to clear the place. Really. Not kidding. Everybody goes gasping out the door.
Sounds like our old German shorthair pointer.
I have a co-worker/friend who was so bad one time at work everyone had to leave the work area. After one such attack I went to the lunchroom for a break where I found my friend sitting at one of the tables eating a very large container of baked beans. I asked him if he was trying to kill everyone. He just gave me a puzzled what-did-I-do look.
