Ok, so we have:

Nick Knowles (stripped off, bellowed, then saved people from car crashes on at least two separate occasions - prob many more by now)

David Couthard (used his angular head to smash through his crashed plane's fuselage and rescue the victims)

There must be others?

Obv people who became celebrities BECAUSE of their heroics (e.g. sullenberger) don't count.

Noel edmonds need not apply.

Should have saved this thread for Friday?
