He has started taking all of his trucks and lining them up. While that may not seem very funny on its own - it is the precision and care with which he does it that is really hilarious.
His is totally focused in on the task and one... by... one... gently... moves... each... truck... til it b-a-r-e-l-y touches the one in front of it.


Once the line has reached perfection, excessive celebration ensues.


Oh, and it isn't just his trucks. He is now lining up ALL of his toys - big and small. This was a clever one... airplane, dinosaur, bus. Why not?


Now, whenever we walk through the house, we are entertained by the orderly lines that Luke has created with random toys.
