Don't any of you ya-hooz let me catch you taking a shit on a sleeping Pekingese! (Not saying I think any of you HAS done that. But, anyway, if you were thinking about it -- don't do it!)
Speaking of cows, I've scripted my instance of the "farting cattle" mod in New Vegas so that when a brahmin or bighorner passes gas, any NPC that's too close will have a "yell and flee" reaction. Fucking hilarious.
