Sit in a circle and have the first person start with "A". They must say any word starting with "A". The following person to the left now repeats that word, and adds a word starting with "B". Keep going until you get to "Z". The last person will have to recite each item through the whole alphabet.
If someone cannot remember an item , or messes up, they are out and must move away from the circle. The next person picks up where they left off.
