I've been slowly making my way through Darwin's "Voyage of the Beagle" and I am often struck by how much Darwin comes across as just a goofy guy having fun. For example, here he is talking about Galapagos tortoises:
"I frequently got on their backs, and then giving a few raps on the hinder part of their shells, they would rise up and walk away;—but I found it very difficult to keep my balance."
@ryanbanderson I didn't know Darwin was a prick.
