Because McHale didn't know who Ruffalo was, he did a Web search, the site said, turning up only the actor's screen credits, which include "The Kids Are All Right," "You Can Count On Me" and the Emmy-nominated HBO film "The Normal Heart." Unfortunately, that information didn't help much in terms of returning lost property, so the good Samaritan decided to tweet at the actor.
"@MarkRuffalo I have your wallet. Found it in a cab in chicago on Friday. Let me know the best way to get it back to you. Thanks," McHale tweeted Saturday.
Apparently, Ruffalo hadn't offered a reward for the misplaced wallet, but that was OK with McHale.
"If [Mark] ever finds my wallet, I expect him to return the favor," he told TMZ.
Ruffalo's rep said the actor was unavailable Wednesday to respond to a request for comment.
