I Don't Know Mortal Kombat: One episode guesting Gene's bandmates Tommy Thayer and Eric Singer has the three of them try their hand in Rock Band (specifically, and obviously enough, "Detroit Rock City"). Let's just say it didn't go over as well as it usually does when they're on stage.
Horrible Camping Trip: 'Alpha Male'. It involves a snake, a bear, and a park ranger with a fire extinguisher.
Insistent Terminology: Gene and Shannon are not married. Shannon is not Gene's wife. Gene is not the least bit shy of correcting people who make this mistake in front of Shannon.
They are married now, so the Trope will not apply to new episodes
Momma's Boy: Gene is a self proclaimed Momma's boy who calls his mother at least once a day.
Overly-Long Tongue: Gene Simmons. Nick too. If Sophie inherited it she's not showing it off on television.
Running Gag: People running over stuff in the driveway.
Papa Wolf: Gene is very protective of 15-year-old Sophie.
