Was i the only one

Who thought Sikowitz was a creepy guy? And a bad teacher? What kind of teacher invites his teenage students over for a sleepover with him as the only adult, go to a foreign country also with him as the only adult, help scam the school for a fancy dinner, hold a contest giving out A's for a whole freaking semester, and shows up to work barefoot. I know this is Nickelodeon and this is Dan Schneider, but really? Who would let that guy near a kid? To me, the most unrealistic character on the show.
