6 year old: Hey mom, do you know there is a type of bird that has been around since the dinosaurs? 
Me:Oh yeah, which one? 
6 year old: The 'raptor', a type pf raptor has been around since dinosaur times.  Mom, raptors are realted to the dinosaur velociraptors, get it mom, 'raptor' is
the 'veloci-raptor' but without the 'veloci-'. 
Me: Cool, good job thinking about how compound words are made.  
Addition and words and dinosaurs combined, good times.

Me: "boys go to the bathroom before bed" 
Them: "ok mom"
They run to the bathroom, I overhear their conversation. 

6 year old: Hey let's pee at the same time
4 year old: Ok, let's make an 'X'  
6 year old: Yes, let's cross the streams! 

Although the streams were crossed, total protonic reversal was avoided...this time
(toilet overspray cleaning was not)

Had the best delaying bedtime tactic ever from the 4
year old tonight.  As I put him in bed, I asked him how many kisses he was going to give me.  His answer: 100 kisses mommy!  Sure enough he gave me 100 kisses,
counting off each one.  (best confirmation that he knows how to count to 100 ever)

Official prescription for a child with slightly
retracted ear drums? 
Twice a day for the next six weeks, he has to blow up a
balloon.  I love doctors with simple science solutions.

The 6 year old was playing with big turtle toy holder in the bathtub. 

"Mom, I am going to design a video game with this turtle.  For the controls, to make it swim forward you will
click the mouse where you want it to go forward and it will travel there. 
To go left, right, or back you will use the arrow keys.  The space bar will make it roll, attack, and eat.  Although, not all at the same time, the... computer will know which one of those three you will need to do based on the game. 
If the turtle tries to swim into a crack too small, he will bump his shell and lose a life point" 

Ok, so he has thought this out. 

Time to get him into LabVIEW so he can make it a reality, that is likely the only programming platform he can start with, since it is icon based and the 6 year old can't exactly read yet.
