Are ENTPs apt to copycat some behaviour, generally unusual and curious? Not just buy the same hat that lady gaga use... More complex and mentally stimulating things...
For example, I was thinking about that episode in
Seinfeld with Kramer (an obvious entp) who wants to keep the Leonardo Da Vinci's sleep schedule and he got almost crazy.
I think to be an entp from time to time... and I do that sometimes (and often I fail) when I read and I am stimulated about some weird habit of an hystorical person I admire.
Maybe only to have the illusion to gain more intellectual/artistic abilities!!
