I was at rehearsal, and my character had just yelled at someone so I was really angry and stuff, and I went backstage and one of my castmates just kind of laughed at me because I looked so angry, and I glared at him in character and said "What are you looking at?" in this really commanding voice (in character), and then I tripped on the steps for really no reason and did this epic comedic fall, my legs went out in front of me and I landed on my butt. He never let me hear the end of that one...
