this may or may not be it
heard this when I was active duty:
I went to McDonald's to get a big mac
They better give me fries or I'll be back
when I got home I looked in the bag
there wasn't any fries so i loaded up a mag
jumped through the arches... crashed through the doors...
aimed center mass and I dropped him to the floor
when I come back there won't be no surprise
they'll give me a full bag of fries!
singing lo-right-lay-o....
