How many NFL quarterbacks threw 5 td passes in one game?

I'm discussing Josh Freeman's greatness on a forum, and I'm using his 5 td game against the Seahawks as a point. I'm just wondering how many other quarterbacks threw 5 tds in one game. I know Kurt Warner did it on '09 and Tom Brady in '07, but who else did it, and who was the youngest? (I'd guess Freeman. :P)
