Amber and Drew's father is an easy choice for the worst parent because he barely qualifies as one. He's long been in and out of his kids' lives (mostly out), and though he occasionally tries to be a dad, the good vibes never last long.

Pros: In fairness he has done a couple decent things: He once stopped Amber from driving drunk, and he gave his kids cards for every one of their birthdays he missed (before, uh, taking off again).

Cons: A lot, but it's hard to get past the fact he's pretty much ignored his kids since they were born.
