Where can you see Bryan Adams rubbing elbows with Leo Tolstoy and Russell Simmons hanging with Leonardo da Vinci? Only on PETA's limited-edition postage sheet from Stamps.com—the sheet honors some of the most influential and recognizable vegetarians throughout history.

Bob Barker and Pamela Anderson—two of the celebrities whose faces will soon be crisscrossing the U.S. on envelopes—unveiled the new postage this morning at the Hollywood Post Office.

Addressing the swarm of clamoring reporters, Pam said, "I'm just happy to be here and happy to be associated with PETA. … [M]y mom is very proud of this." And the inimitable Bob Barker joked, "I was happy to do it when they told me I didn't have to die in order to [be on a stamp]!"

The postage sheets are available at PETA's online store, just in time to grace your holiday cards with a reminder to loved ones to think before they eat.

In honor of Father's Day, here are some fathers who are friends to the furry, feathered, and finned. We had way too many great dads like Kevin Nealon, Bryan Adams, Woody Harrelson, Iggy Pop, and Chad Ochocinco to choose from, so here are just a few of the fellas who make us glad for awesome dads:

• Ron Artest loves being a dad to his family, but he knows that dogs and cats are happier without their own brood of offspring and should always be spayed and neutered.
• Vegan dad Casey Affleck is starting his young sons out on a compassionate note, setting a great example by speaking out about the cruelty of the meat industry and lethal steel-jaw traps.
• Alec Baldwin is a proud pop who would never hop on a horse-drawn carriage.
• Tony Gonzalez and his wife could win an award for most beautiful parents, and this fur-free dad has a beautiful heart too.
• Happy first Father's Day to Carey Hart. He and his wife, Pink, seem like they'll be fun parents for their new baby girl, but they'll be pretty serious when teaching her about cruelty to animals.
• With a dad like Tommy Lee and a mom like Pamela Anderson, the Lee boys may grow up to work at PETA! We love any dad kind enough to give a homeless man $100 with the request, "Just don't buy KFC."
• Sir Paul McCartney obviously instilled animal-friendly values in his children, who are all vegetarian, including daughter Stella, who is also a cruelty-free fashion designer.
• Power dad Russell Simmons has been running with PETA for a long time, and he shows his children that being successful and being kind to animals go hand in hand.
• We're not the only ones celebrating fur-free father Amar'e Stoudemire. The Knicks captain is receiving a Father of the Year Award in New York City today.
• There's not a woodland creature who wouldn't love Forest Whitaker, and we're sure his kids think he's pretty darn great too.

Canadian Rocker Bryan Adams, a vegan and a friend of PETA who has donated his talent as a photographer to help us create our ads, took it upon himself this week to let John Bitove, the CEO of most KFCs in Canada, know exactly what he thinks about KFC suppliers' treatment of chickens. Adams said, "[Y]ou could set your company apart from KFC operators in the U.S. and elsewhere by eliminating the worst abuses on these birds, as … chickens killed for KFC in Canada are scalded to death in tanks of hot water, suffer broken wings and legs, and worse."

Thanks Bryan, for, um, "Everything You Do" (I'm going to be singing that song all week now).
