I always knew it! I'm pretty sure he was also buying time while that attention whore Peach was climbing out the back window.... 
Well that just provides evidence that toad isnt flipping you off, he just hasnt been able to bend the fingers back into shape he was just "using" . Prolly has arthritis and if he keeps any of his joints in one position for too long it takes a sec for them to flex back. This might also explain why Peach always seems so relaxed and calm at the end of the game.

Then again, Peach seems to have a thing for short guys too... Poor Luigi, if only he was shorter...
