This guy - he may be a member of DNF - came to his doctor office for a checkup.
He was in the room with the doctor and just shake his head when the doctor asked him "what can I do for you today?". He then grabed a piece of paper and wrote down: "something is wrong with my tongue, I can't talk!".

The doctor then looked at his tongue and saw the tip of the tongue bent backward to his throat. He can then talk after the doctor fixed him up with a liquid solution called "Liarmycine".

"OK, can you tell me what happened" the doctor asked.
He guy replied:
"I tried to buy some 4-letter domain names and the seller said they are pronounceable, then I could not talk after trying to pronounce 5 names in 30 minutes".

The doctor said "OK I understand. Take the solution bottle with you and make sure you soak your tongue for 15 minutes before trying to pronounce the names again".
