Tongue twister leads to embarrassing moment in Drama Class

Back in 11th grade, I took Drama Class. Mr. Peters was the teacher. One day, he had us do tongue twisters in class. It was a tremendous learning experience, illustrating that any dramatic performer can mess up a line in a performance.

The line I was to say was "Three gray geese in a green grass grazing. Gray were the geese and green was the grazing." However, what came out of my mouth turned the unsuspecting geese into creatures who live an alternative lifestyle (I left out the "r" in "gray"). My freudian slip cracked the whole class up in a memory I still have to this day.
