Balki and Mary Anne expect Larry and Jennifer to set a wedding date but they're too scared. To help them, Balki gives them an official marriage test to see if they're right for each other but things don't go as expected. In the end they set the wedding for September regardless of what the test says.

Balki convinces Larry to become a volunteer fireman but after the fire chief wore him out, Larry refuses to go back to the fire station until he discovers that Jennifer gets really turned on by firemen. However, the only fire they get to fight is in the fire station.
