Sasquatch or Squamous?

The other day I was in the dermatologist's office, and for the life of me, couldn't remember the type of cancer called "squamous."

I stuttered, "It's squa-- squa-- Sasquatch!" Then I burst out laughing, knowing that wasn't the right word, but the only word which filtered to my lips.

As my husband and I walked down the hall at the end of our visit, we could hear the laughter follow us as our PA told the nurses the story of my word substitution.
