Just yell "Bang!" loudly enough for some coworkers to hear, then claim you were shot. Have a buddy pull up in a box van with a posterboard "cross" on it. Tell him to wear a white jacket.
Viola! You're outta there!
If I've learned one thing from watching The Simpsons and The Family Guy, things like this always work!
