I AM JOE. I am a Wal Mart schlub in flyover country who changes my own oil and unclogs drains without a license. I smoke and drink beer and toss the football in the front yard with my kid, and I figure I can fend my way without handouts from some Magic Messiah's candy bags. Most everyone in my family and most everyone I grew up with is another Joe, and if you screw with them, you screw with me.
And no, you can't make bumper stickers, shirts, etc. for profit using the above graphic.
