For me it's "did you hysye6du3h my cookie?" "I'm sorry, did I what your cookie?" They go into an in depth explanation and definition of eat. "No, no, the word, I just need the word. I heard everything except the one word" "Oh, eat. Did you eat my cookie?" "How did you mumble eat into 3 syllables? And no I didn't eat the cookie... it might have been the cat though"

Could be worse: "never mind."
