The second one "I will have two scoops vanila!"
The first one thinks for a moment and says "Hmmm...better you write the order down, You may forget it."
The second answers back "Ah, no need, the ice cream shop is just across the road"

The first one asks "Where is the ketchup!?"
The second "Damn, I forgot!!!"
Upon which the first one "You see! I told you to write it down!!!!!!
