Heaviest member link on sidebar to the fattest member's featured profile.
Could we maybe get a link to whoever is currently the heaviest active member on the site in the sidebar? It could just query the weight database and whoever has the highest weight from a recent change is featured as the fattest member. There could even be an opt-out checkbox on the profiles for folks that prefer privacy.
The whole purpose of this site is for dude's who like fat dudes, so why not showcase the biggest? It might even help inspire some folks to want to really give it a go and see how big they can get.
