I can imaging this now:
"Hello Im your teacher today"
"My teacher?"
"No, look at the names above peoples heads, Bob is your teacher"
"Hey Im your teacher"
"Ok so Bob is our teacher?"
"No Im your teacher, Bob is their teacher"
"To open the tools menu press Q"
"Hit B and you can select bricks from the menu"
"I hit B and their were no tools"
"No, you hit B for bricks"
"I thought you said to hit Q for tools?"
"I did, but they are doing bricks"
"I hit Q and their are no bricks!"
"To jet hit the right mouse button"
"What does the Y button do?"
"What does Ctrl-K do?"
"Its for team chat"
"Oh ok"

"HEY IT DIDNT WORK!!!"
"No I was talking to the guy about Y"
