They say laughing is free medicine

and we all use it

but why do we laugh at others when they

fall

trip

make mistakes

when we all have been through it

why do we laugh at the sound of farts? 

we all do it

why do we laugh at other laughs?

no matter how much we've heard it

we all know its heard to hold a laugh in when someone

falls

farts

trips

its uncontrolable

and hopefully we all realize that

otherwise i think this world

would be full of sad people

just because we laughed at them

falling.
