There are lots of Rochester comedians, but only one married comedy couple. As comics of a certain age (mid-50s), Lisa and Scott Fybush produce Comedy On Deck shows in their back yard every summer. To many younger comics, they’re the local “comedy mom and dad,” and they’re real-life parents of two young adults. Their comedy shows have been fan favorites at past Fringe fests. This year, for the first time, they’re sharing the spotlight as co-headliners in their own new show.
