Just walk in and say " here is my 2 weeks notice in writing" Smile and remember YOU are in control..If he were were to start yelling .. Just calmly smile and repeat "here is my 2 week notice" say "thank you " and walk away.

You have another job.. Don't feel scared.. and if your ole boss is a yeller like that even more reason to be polite .. angry people don't know how to react to calm people.

Good luck
