Classroom Interruptions

With Thanksgiving being just next week, students are DEFINITELY showing that they're ready to be out of school. They seem to be more antsy, they don't really want to do anything and they've kinda had this idea that since it's the week before break that they don't have to do anything. Well... that's obviously wrong.  Mrs. Hastings and I are no strangers to classroom interruptions.  We have one difficult class in particular.  It's really hard to explain the class atmosphere to someone without them actually just coming in and seeing it.  There's one student in particular who, well, is VERY attention hungry.  He starts singing or humming randomly in class, stares at other students, makes inappropriate comments, makes the other students feel uncomfortable, plays imaginary drums and, recently, decided that we was going to stand up, stretch and then lay down in the middle of the floor and take a nap... Yea... All of his teachers have been struggling with him.  Generally, if there's a negative classroom interruption and students aren't willing to bring it back in to the lesson, I remind them that we don't have to do fun activities in games in class and have on several occasions reminded them that they can copy their vocabulary lists twenty times for the rest of class.  I hate being the bad person and there are some classes where I just always have to have a strong hand.  I don't think they always realize that the class could be so fun and easygoing if they just went along with what we did and I didn't have to keep bringing them back in line... It's pretty frustrating...
