Look a likes?

[Major Tom]

Sometimes old joe has black pupils and coughs a lot and has trouble walking. Other times 'his' pupils are blue, doesnt cough and can ride a bike 20-25 mph while waving, doesn't stumble when walking. Real joe fell down the airplanes steps 3 times, can't find the way into the White House and needs notes and tele promters to speak!

[Allen]

The banjo player from Deliverance?

The real Joe will have poopy pants, can't walk, can't talk, can't think, and give everything to the taliban.
