And seeing as he's 100% committed to following through on his internet promises, we're excited.

David Harbour, fresh off featuring in a high school student's yearbook photos, is back on Twitter making promises to fans in exchange for retweets, this time agreeing to officiate someone's wedding.

Twitter user @ErickaElizabth made the request Monday night and it quickly got people's attention, racking up likes and retweets until Harbour himself chipped in.

If the new trend becomes your favourite actors trying to outdo each other by providing services for their fans, we're all in.
