PAIN

(Grind)  (Add)

You only need one female character to do both Grenade-a-Maid and Glass Lass, so if you've already purchased one for G-a-M, just use her. The Fat Princess character is free, so you can download her without having to buy any extra content for the game. Pick a level of Mime Toss using your purchased character, and just ignore the mime. Launch through each pane of glass until the game is over, and start over. Your score will be something like 5 minutes, but each broken pane of glass counts.
