For the "Can I feed my snake something other than rodents?" Put a snake sitting there with a cheeseburger looking confused.

A "book worm" snake--- reading a really thick volume of something---for the "I know a guy who's kept snakes for years..."

For the "Aren't you afraid the snakes will eat your rabbits... Aren't you afraid the snake will eat you?" Maybe a giant rabbit sniffing a tiny little snake, who's tongue-tasting back? (I think it would be really funny to show a little snake trying to constrict someone's big toe or thumb or something, and barely able to get it's mouth open around it, but I also think that might give the wrong impression to those afraid snake bites... funny image though )
