When David, Andrea, Mark, and Tammy go on a cruise together, David and Andrea unexpectedly rekindle their romance. Mark's preoccupation with reeling in a big fish to outcompete Steve DelVecchio leads to him catching a whale that jeopardizes the safety of the entire cruise. Meanwhile, Hank goes on a date with a mermaid that goes awry when she reveals her distaste for hot dogs.

Mark buys himself a Superbowl ring and leverages it to get special treatment at the Eagles game; Hank has an adventure with cutting-edge mascot technology.

Mark throws his hat into the ring as an Ad Man after being shown up by a group of execs.

Mark accidentally murders Hank with a crossbow while hunting a deer.
