When Greg was first approached to play one of the title characters on My Two Dads, he turned it down right away, because he didn't want to play a TV dad. Later, his agent called him and asked him to just meet with series creator Michael Jacobs. After looking at the script and doing a read-through, Greg finally accepted the part.
Greg's first job on Broadway was at the age of 17 when he sang in the original production of Jesus Christ Superstar. His second role was the lead (Danny Zuko) in the original stage production of Grease.
Greg: (about Sam the chimp, who he starred with in "B.J. and the Bear") Generally, Sam's a very mellow fellow. If he weren't, this series could have been a nightmare.
