Play Horde of English Zombies. If the zombie speeches English as poorly as I did in writing the title, shot him! If they're word bobble seem's correct, let him go.
Okay, that's enough deliberately bad English. I'm not saying there won't be errors below, but if there are, they aren't deliberate.
It's not a great game, but for it's price (free) and amusement factor for ESL teachers, it's worth a few minutes or even more.
