What's Up with Sarah Silverman and Heroes?

Maybe I'm the only one, but when I was watching last week's Sarah Silverman Program, I was struck by the latest in what seems to be a long line of connections to the show Heroes. Viewers of both shows no doubt recognized actress Adair Tishler–who played the young version of Laura Silverman–as Heroes' Molly Walker. This comes after last season saw a guest appearance by Masi "Hiro" Oka, and in the wake of a TMZ video of Sarah and Hayden "Claire Bear" Panettiere hugging at LAX!

But wait, there's more! Last season's Sarah Silverman Program episode The Muffin Man featured an appearance by Brad Grunberg as Fat Boyfriend. Brad Grunberg is the brother of none other than Heroes' Greg Grunberg!

Could a Sarah Silverman guest-spot on Heroes be far behind? What would her power be? The ability to turn poo white?

Here's a preview of tomorrow's episode:
