Gazpacho. I can make my mouth form the correct sounds, but not without all of my concentration.
A few years ago I was waiting tables and the soup of the day was gazpacho.
I greeted one of my tables and began to tell them the specials and I slipped.
The two very nice gentlemen were very amused when I informed them that our soup that day was gestapo.
I, on the other hand, was mortified.
