A man was concerned that his wife was losing his hearing so he spoke to his doctor about it. The doctor suggested standing 60 feet away and asking her a question in a normal speaking volume. If that didn't work, try 50 feet. If she still couldn't hear him, stand 40 feet and so on.
So he went home and tried it. He asked, "What's for dinner?" at 60 feet, 50 feet, 40 feet, 30 feet with no results. Finally, he walked up five feet away from her and asked loudly, "What's for dinner?"
"GOLDAMMIT, FRED, FOR THE FIFTH TIME, IT'S CHICKEN!!!"
