Ben Affleck made his first public appearance since marrying Jennifer Garner last night (08SEP05) when he stepped out on pal Jay Leno's late night TV chat show to sign a motorbike.

The yellow Harley Davidson is to be auctioned off to aid the Hurricane Katrina relief effort.

Affleck couldn't resist poking fun at his friend Matt Damon during his brief appearance.

He joked, "Next week I'm gonna be back and we're gonna donate Matt Damon."
