An archaeologist and 2 historians are sitting next to each other on a plane.
The archaeologist took off his shoes.
One of the historians asks the archaeologist to get him a coke.
He says yes and when he gets up the historian spits in his shoe.
When the archaeologist got back the other historian asked for a coke.
When the archaeologist left again the other historian spit in his other shoe.
When the plane landed the archaeologist put on his shoes and realized what happened and says.
The fighting between our professions has to stop.
The spitting in shoes the cumming in cokes.
