 * having the whole neighborhood's houses taken away so he can be alone because they were gossiping behind his back
 * trapping his family in goo so he can spend the holidays alone
 * not the worst but he's pretty selfish when the house gets flooded and he tries to be the big man who saves the day (he sucks at making decisions)
 * doing a "DIY" plastic surgery on his daughter so he doesn't get in trouble
 * running a sweatshop with illegal mexicans so he can earn money
 * dressing up as a bully and beating up steve multiple times
 * ruining every aspect of brett's life so he can be closer to god (I.E, blowing up his house, destroying his family, etc)
 * framing franicine for murdering her friend (bullock did that) and putting her in a really dark place just so francine wouldn't say "i told you so"
 * generally being an ignorant xenophobe
