I'm convinced it's all just Native American humor...I can see it now....Two Iroquois watching some dumb English guys tromping around the woods in the middle of summer in their hot dark wool and the first Iroquois says to the second "Watch what I can get these fools to say....We call that river Susquehanna...good luck spelling it" Then after the English go back to town they laugh and say "That was pretty funny let's go see whatelse we can get tehm to say..."
