Our high school had a dress up day, and one of the cuter lady teachers dressed up like the cartoon dog Muttley, of "Dastardly and Muttley" fame. I thought it would be funny to comment to the teacher as I walked by that my Dick Dastardly costume was getting dry cleaned, just to let her know that I got the reference, since the cartoon wasn't very modern. As we locked eyes, it happened. I was able to get out "I have a Dick---" before everything cut off. Full stop. I was able to get the "---Dastardly" out with some panicked hand waving to let her know there were more words in the traffic jam, but not before her eyes went wide, her jaw dropped, and she inquired as to "who do you think you are ah blah" or some such. We laughed about it later, but still. Haunts me sometimes.
