that sounds very similar to something i did with 2 other mates in 2nd grade.
at lunch time all 3 of us stood under a tree and pointed to a specific leaf on a certain branch at the top of the tree.
the leaf was not the point.
we just stood there and said to each other "Holy Crap.. Look at that... Look at it... wow... can you believe it... Look at that"
and then someone would come along and say "what is is"
and we'd be pointing at nothing and saying "can you see it .. it's right there, look at it.. can't you see it"
a few more people wander over
and then a few more
and then ONE BRAVE SOUL SAYS "i see it.. i see it" LOL
then around 5 people follow the Queue
and we slowly backed away from the crowd and went away to continue playing handball LMFAO
it was funny shit, something i'll never forgoet
they stood their for the remaineder of lunch time looking at nothing, there was like 50 kids all up. or close to it.
