I went to a school that serviced out of town farm kids. During grade 8, tobacco chew was really big with some of the farm teens; our math teacher allowed us to drink pop so some of the teens used the "sipping" of pop as a way to spit. Now every one in our class knew what was going on except the teacher; one of the girls came back from the washroom and had a major brain fart. She grabbed one of the guys cans thinking she was being funny stealing a swig of pop but instead took a big swig of tobacco spit. She booked it out of the classroom much to our enjoyment and the teacher had absolutely know idea what was going on
