In Diary of a wimpy kid Rodrick rules what did Dad do to make sure he home when band practiced?

In "Diary of a Wimpy Kid: Rodrick Rules", Greg's Dad didn't do anything specific to ensure he was home for the band's practice. Instead, it was Greg's Mom who made sure Dad was home.

She deliberately left the car keys in her purse (knowing Dad would need them) and told him to "go get the car" right as the band was supposed to start practicing.

This forced Dad to stay home, preventing him from leaving for his usual Friday night poker game and ensuring he was available for the band.
