Kudos to the Arizona Diamondbacks, who have turned utility man Ryan Roberts' passion for tattoos into a unique promotional giveaway.

At Saturday's game against the Giants, the team will hand out Roberts-themed tattoo sleeves to the first 20,000 fans through the turnstiles. Roberts is an unabashed ink junkie, with more than 30 tattoos adorning his body and a "Tatman" line of apparel.

So if you want the coolness factor of a tattooed forearm -- without any fear of buyer's remorse -- Saturday is your lucky day.
