To wear or not To wear?

my friend just got kicked out ofschool for weed and we miss him so made t shirts to wear on grit day(a day were our school dresses up for the day before spring break)........they are green and have a picture of him on the back.....no problem...it would be ok....but.. our whole sophmore cl got a talkin to by the headmaster about weed and **** like that......we already bought the shirts.....and there pretty ...should the 4 of us still wear them?
