This story from a buddy of mine with 3 boys (all under 10) ...
The whole family is out having breakfast at the local diner, about half way through the meal a pair of cops walk in ...
The 6 year old goes "Hey Dad, the cops are here... Why do you think the cops are here, are they here to get someone?"
My buddy says "Relax, they're probably just here to get some breakfast too".
The kids seemed amazed at this, that cops actually ate the same kind of food that they did, but once the cops sat down thought it was pretty cool that they were having breakfast right next to a couple of the town's finest. Throughout the meal the kids kept pointing at the cops and asking Dad more questions about them, normal kid stuff ... "like is that a real gun", "What's that thing for?", "Where's their police dog?" and so on.
After eating, the 6 year old (the one with all the questions) needs to go to the bathroom, so my buddy sends him off to the bathroom with the oldest son. The 2 boys get to walk right by both cops on their way to the bathroom and are checking the cops out as they go. Just as they reach the door to the bathroom, and are pretty much on the opposite side of the diner, the kid shouts to his Dad ...
"HEY DAD!!!! Which Cop do you like more? The FAT one or the BALD one?"
