A pilot recently got a little distracted when calling in over Illinois:

Chicago Center:
"56Y, please say destination."

56Y:
"That's Mike Gulf Whiskey, ma'am."

wingman:
"I think he meant to say 'Mike Gulf Yankee.'"

Chicago Center:
"Is that correct, 56Y?"

56Y:
"Yes, ma'am. Sorry. I was thirsty."
