These parts I remember three kids and grandparents.

1. the class room. Where they were taking test and the kids try to cheat using an eye patch. The other kid uses notes and throws them like throwing knives. The kid throws one and it lands on the teachers hair but she doesn't know it's there.

2. the grandparents teach their grand children and this fighting scene was a lot of beer cans on the ground and the one who touches the ground first loses.

3.the kids get an assignment from their grandfather to steal their grandmothers jewelry. The kids get inside the house dress like ninjas. The grand mother pretends to be asleep and the grandma was having fun with this back. Later on the fat kid give it a try and wakes up grandma and she pretends to be like a robot or Frankenstein. The fat kid cries and cowers next to a wall.

These are all the scenes I remember. I've been searching for years to find this.google didn't help. I saw this 22 years go. I would like to know the title of this movie.
Thanks

Urgghhhhhhhhhh. Why have you done this to me. I also cannot remember the name of this movie for the life of me.

I do remember a scene where all the boys are being weighed in a nurses office. And one of the boys manages to freak out the nurse by holding his breath in and increasing his weight.
