"i thought they were joking, professor."

so here's the deal...

i have a presentation at 9:00 in the morning. it's a group presentation. it's over kashmir, the pakistan-india conflict and nuclear weapons. there are 3 of us.
my group's really not bad. pretty typical college students, a guy and a girl. they're also really nice to me. they offered to present my third of the case tomorrow if my voice didn't get better. see, all-around nice kids.
they think that it would be a good idea to have a bit of class participation. so far so good...i'd like to have a little feedback as well. HOWEVER, they think that the best way to have the group participate would be to put sacks on half of the class' head, thus marking them as muslim, and therefore pakistani. and the other half of the class will be marked with none other than a red sticker on their forehead, flagging them as indian hindu. and we will procede to tell them what is happening to them, and how they should look. for example, you're getting bombed; put on your angry face.
ARE YOU KIDDING ME?
i'm naive. i didn't know. surely the prof can't take it out on me. too much.
