Yeah, though in this case, it fit in well with the fact that my relative had recently heard the "There's no 'F' in broccoli" dad-joke:

  Customer: "I'd like a pound of broccoli, please."
  Grocer: "I'm out of broccoli."
  ... repeat 1 or two times
  Grocer: "How do you spell broccoli?"
  Customer: "B-R-O-C-C-O-L-I."
  Grocer: "You left out the 'F'."
  Customer: "There's no 'F' in broccoli!"
  Grocer: "That's what I'm trying to tell you!"

My apologies for any annoyance this joke has caused.
