Private is a bit fuzzy on who he is and his role in the group. Since he's not so sure of himself, Private is completely open to every experience. The zoo can be a rough place (especially the Reptile House) and Private is a little too obviously naïve for his own good. Private's openness makes him the most likely to party with the lemurs for better or for worse.
"Is it... Safe?"
"Goodbye... old telly chum."
