SFB sensei, number 2

so back in october our dear and lovely english rose, KAT, wrote about a troublesome teacher who she affectionately named "shit-for-brains sensei". here is a posting describing the wonderful creature and a couple of comments which followed.
dare i say this but...i feel as though i now have some competition at one of my schools.
there is a middle-aged male teacher who came to one of my schools from a private school in august, and had never taught with an ALT before. he speaks some (crap) english, but i have absolutely no idea what exactly he does at this school. he doesn't seem to have any specific classes he teaches, other than the 2nd grade select class once a week. the rest of the time he sits at his desk, staring off into space, reading the dictionary, or (shudder) staring at me.
he is a horrible disgusting man. he is a complete wierdo. i can't even describe his creepiness to give it justice. he's got long, greese-wet hair which he combs over his bald head. he stinks of stale cigarettes and his breath smells from across the room. he got all frustrated with me in a close-talker kind of way when he asked me what the difference between the verbs "to begin" and "to leave" were and i explained politely that the two verbs have nothing to do with each other and that they can't be confused. he has this horribly annoying habbit of telling me something, i answer, and then he continues to lean over me, with his bad breath, staring at me...for an uncomfortably creepy amount of time while i shuffle around, look at him, look back at what i'm doing, 'ask him OK??' and he just stares until after an agonizing minute or so, he'll say something ridiculously stupid.
today i had the pleasure of teaching with him. he'd asked me to plan for the class about two weeks ago, to which i happily obliged. when i went up to him yesterday to explain and confirm the lesson plan, he pointed out that the warm-up activity i'd arranged (which i often do with my students at all my schools and have been for almost 3 years now) would be too difficult for the students, that "they can't do it..i think". i just looked at him and said, "yes they can, i always do this activity". and that was the end of that.
we went up to the class for 4th period today and it was obvious that the kids have absolutely no respect for this guy. at the beginning when he was trying to get them to do the greetings, they were just yelling and laughing at him and making fun of him. he started SHOUTING right away "CLOSE THE DOOR!" and "SHUT YOUR MOUTHS!" and i just kind of stood there looking strangely at him. finally i decided it was going to have to be me that gets control of the kids. so i did my normal routine and the kids were very good. i just basically took over the class after that. it's just so obvious that this guy just doesn't have a clue. why do people like this become teachers?
if he wasn't so pull-my-hair-out-skin-crawling annoying and creepy, i might actually feel sorry for him.
