Don't forget at the 2008 GF I have never seen so many Manly jerseys at the Olympic Stadium ever, and yes many of them came out of mothballs as well.
I have a few mates on Facebook that are Bunnies fans, they have hardly said boo to me (about football) for years, until last year AND then NOT after the result from last year until recently.
They don't attend matches, are not members BUT have pulled their old jerseys out, taken photo's, replaced their profile picture and all they are talking about is a Bunnies victory.
So there are LOTS and LOTS of "bandwagon" supporters out there for every club, ours included.
