Well, over at les-mathématiques.net that very question was asked, and it has been shown the following.
Define a Siamese to be a quadruplet 
Then, if there exists an element of finite 
On the other hand, the only infinite Siameses are of characteristic 2, namely the purely transcendental extensions of 
I think these results are quite interesting and should be incorporated into any undergraduate algebra curriculum.
