Creme de Menthe Bars (Original)

Melt the 1/2 c margarine (about 35 seconds in the microwave).
Add the egg, graham crackers, cocoa, powdered sugar, and vanilla.
Pat mixture into a 9x13 pan and put it in the freezer.
Melt the 1/2 c margarine (about 20 seconds in the microwave). Add creme de menthe and 3 c powdered sugar and beat with a mixer.
Spread on top of the crust (it will be runny). Chill 1 hour in the refrigerator until good and firm.
Melt the 1/4 c margarine and chocolate chips on the stove just to the melting point, so that the chocolate is good and thin but not too hot.
Spread *seriously* fast on chilled green stuff.
Chill at least 20 minutes, but cut the bars before it gets too cold (check every 10 minutes after the first 20).
