Well, the "fast" option is to use connect/netcat:

ssh -o 'Proxycommand ssh bastion connect yourhost 22" yourhost

The disadvantage is you need connect or netcat on the bastion host.  (I 
also had problems with netcat not exitting but apparently recent 
versions don't do that).

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
