Either I am easily amused or my friends are idiots

The list would comprise of the following:

1) My brother shot a piece of hamburger out of his nose.

2) one of my co-workers ran over a frozen dead cat (I am not sure why that was so funny but at the time it was hilarious)

3) my friend put on his seat belt to eat his sandwich

4) my friend ran into a glass window pane because he thought it was a doorway. (Seriously this happened)
