Saturday low information voter joke

Mom walked into the bathroom one day and found  her low information voter son furiously scrubbing his dick with a toothbrush and toothpaste.
"What the hell do you think you're doing, young man?!" she exclaimed.
"Don't try to stop me!" He warned. "I'm gonna do this three times a day, because there's no way I'm gonna get a cavity that looks and smells as bad as my sister's."
