It's A Grand Old Flag

It's a grand old flag, it's a good plastic bag
and we get it on all of our clothes.
A guy can play the live-long day and
have it wherever he goes.
It is lots more fun than a doll or a gun,
you can wave them around like flags.
But should old acquaintance be forgot,
keep your head out of plastic bags!

This is the way I remember this wonderful parody. I can never remember the real lyrics, as the above successfully replaced the real lyrics in my memory bank. :)
