My all-time favorite joke: The Forgetful Couple

An elderly couple are sitting in the living room, and the old man gets up, and says "I'm going to the store to get myself a soda, do you want anything?" His wife says "I'd like an ice cream sundae. Here, I'll write it down for you so you don't forget--" "I'm not going to forget," he waves his hand at her dismissively. "Ice cream sundae." "With cherries and chopped nuts. You'll forget, I'm going to write it down for you." "Woman I'm not senile! I won't forget! Sundae with cherries and nuts." "And whipped cream. You're sure you won't forget all this? You forgot the last time. Please, I'll write it down so you won't forget." The old man gave an annoyed sigh and left the house. He returned and handed his wife a bag. "Here you go, I didn't forget." She looked inside the bag and found a toasted onion bagel. "Yes you did! I told you you would forget, and you did!" The old woman threw a fit. "You forgot the cream cheese!"
