1) Ed and Al wouldn't get through the metal detectors without being detected, I mean without the alram going off.
2) Al would not fit through the metal detector anyways. He would knock his head off and everyone would be screaming because there's nothing inside the armor.
3) They would have to inspect them both...
4) Ed would get mad. They would have to pull Ed's arm and leg off and he'll freak out the entire crowd.
5) Al would be taken by the SWAT team.
6) If Ed ever abroads the plane, his metal arm and leg will have to be stored in the cluff department where everyone's bags are.
7) If Al ever made it on the plane, he would also be stuffed in the cluff department like he was on the train.
8) If Ed was to get his arm and leg back, he would scream because it hurt so much to put them back on. People would be staring at him.
9) While on the plane, Ed would be missing body parts and no one would wan to sit next to him.
10) If Ed had to use the restroom, he would have to either hop on one leg or crawl his way there.
11) Don't even want to mention how he would use the toliet...
12) If Ed uses a wooden leg...
13) People might call him "Peg leg Ed." People calling him a shortie is enough!
14) He might get splinters from the wood!
