one of the kids, pointing at a dinosaur leg showing all its muscles: "look, dinosaur muscles!"
shelby: "a big slab of meat, that's what i like!"
tiina: *cracks up*
shelby: "that was slightly inappropriate..."
tiina: "slightly."
shelby, pointing up at the stone ornaments - a devilish head with horns: "oh look at that thing, with the horns. it's like me. horny."
and shelby again, pointing up at the top of the next stone pillar, displaying a cat figure: "look. a pussy."
so that was plenty of natural history for one day. and you can imagine what it was like when we got to the human biology section...
