It was a busy weekend for Tyrese Gibson, what with the opening of the second Transformers film last Wednesday, the BET Awards on Sunday and promoting his new comic, Mayhem, on Twitter in between.

With more than 160,000 followers on Twitter, the actor started encouraging them to call 1-888-COMICBOOK, the number for Diamond's comic shop locator, to find a local comic shop and ask if they 'd have his Image Comics series when it comes out in August.

He went on to mention several shops that fans reported would carry the book, and even gave out the phone numbers of shops that hadn't heard of it. Then he went on to call a few of them himself.

"I just called the shop.. Attitude was crazy call her and make her aware of MAYHEM," he wrote after calling Lone Star Comics in the Dallas/Fort Worth area. He also tried to call shops in New York and New Jersey.

"It's STANDARD in the comic book industry to ORDER ONLY 2 or 3 copies I think it's PURE B.S!! PRE-ORDER 400 and Make your CUSTOMERS aware go!" he said later on Saturday.

Mayhem #1, written by Gibson, Mike Le & William Wilson, with art by Tone Rodriguez, is due in August.
