A Man with a Truck in a Park

I saw a man today walking a toy truck,
Not a boy, a man, a real genuine schmuck,
He was walking it using a remote control,
Walking the park to and fro a slow stroll,
Why would a twenty plus man walk a truck?
In the park, with remote, must be out of luck,
Maybe he ran out of dolls and balls or a duck
I think i already said the guy was a schmuck.
