Higher Spins and Stringy AdS5xS5
  In this lecture I review recent work on higher spin holography. After a notational flash on the AdS/CFT correspondence, I will discuss HS symmetry enhancement and derive the spectrum of perturbative type IIB superstring excitations on AdS5 in this limit. I will then successfully compare it with the free N=4 SYM spectrum obtained by means of Polya theory. Decomposing the spectrum in HS multiplets, I will eventually sketch how ``La Grande Bouffe'' can be formulated a` la Stueckelberg.
