I'm the same as Lazy. Sorry!

Thom, seeing no good course of action in this situation, drowns his sorrows with the premium whiskey.

Seriously though, I can't think of anything we can do. It seems our weapons aren't going to do much good, which suggests that poisoning it is our best option. However, anything from the brewery that we feed to it is likely to get it drunk, which...probably won't help matters.
