The Adventures of the Robot Friends

We have a routine at night that always involves a story, a made up story that is, by Anna or me.
There are three options, depending on how early we get to bed.

1. A regular full length made up story.
2. A teensy weensy - this is when there is no time for a full story, so this option is about one minute long- and usually really silly.
3. A teensy weensy wishy - this is when there is pressure from both boys for a story that's just a little bit longer than a teensy weensy...but still much shorter than the regular story #1.

Tonight we had time for a full story.   The boys named it the Adventures of the Robot Friends.
(The name came after they heard the story)

This story involved 4 robots.  Beep beep bop, Tin Tin, R2D2, and Schwa.  They all lived on the planet neptune. 
The tale began when Beep Beep Bop headed up to the top of a mountain with his little robot body.
Soon, Tin Tin came up and joined him.  Followed by R2D2, and finally Schwa.
The fun part of making up this story is that I got to tell the whole story in a robot voice.  Wicked Fun!   Anyway, after all robots made it to the top of the mountain they all came down again because Schwa said there was a robot man giving away free things.
They all lined up.  Beep Beep Bop was first.  He was given a button.   The Robot man said, "Put it on and it will work for you."
Tin Tin got a switch.  The Robot man said "Put it on and it will work for you."
R2D2 got a lever.  The Robot man said "Put it on and it will work for you."
Schwa got a light bulb.  The Robot man said "Put it on and it will work for you."
All the robot friends put on their free things.   When Beep Beep Bop pushed his button, he farted.
(You can imagine my boys laughter at this surprising element.)  When Tin Tin flipped his switch, he peed.   More laughter.   When R2D2 pushed his lever, his Robot pants fell down.  And finally, when Schwa turned on his light....nothing happened.   Huh?   All the robots leaned in to see if the light would turn on.  Nothing.  They moved closer still.  Then...they heard a voice coming out of the light bulb, singing in a sweet soprano - "You light up my life....you bring me light...."  My boys cracked up so hard!    I ended this crazy story after this, but the boys demanded more.  They want it to be a chapter story that I tell night after night and keep adding on to. 
I had to write it down so I woudn't forget all the details.  
I see that this might lead to something.  The boys want me to keep adding more robots that represent their friends.   So far, Anders has claimed Beep Beep Bop, and Kuba has claimed Schwa.   Tin Tin and R2D2 will be their friends Sebastian and Julian.   Kuba's little friends are being added in chapter 2.
I can imagine I can get them to draw the robots...etc.  

This is our life at night.   I think ths is going to keep me from getting old.... using my imagination like this on a nightly basis.  And just as a disclaimer, not all of my stories involve potty humor.
