All good ideas, each done one time in some long-past year, and when any idea is done once, it becomes a tradition that must be done every year. "You're going to do that with our class, aren't you?"
Even that is well and good, until it gets to a certain point. . .
p.s. "Babe Day" - Well, when the biology students finish dissecting a pig, doesn't it seem appropriate to bring in pig food and watch the movie "Babe" as a celebration of finishing? The spread included bacon, sausage rollups, ham sandwiches, pork rinds, pork and beans, barbecue potato chips, and pig cupcakes. The kids get more and more creative every year.
