For those who would like to try the toilet paper fiasco, but
would like to limit the toilet humor in the classroom, try this
alternative: instead of asking the students to take sheets from
a roll of toilet paper, pass around a bowl of small candies such
as M&M's and ask the students to take as many as they would like,
but not to eat them yet. Then ask each student to say something
about themselves in English for every piece of candy that they
have taken.
