ssh server-one -t ssh user@localhost -t ssh server-two

From man ssh:

     -t      Force pseudo-tty allocation.  This can be 
             used to execute arbitrary screen-based programs 
             on a remote machine, which can be very useful, 
             e.g. when implementing menu services.  Multiple -t
             options force tty allocation, even if ssh has no local tty.
