With some of the accusatory comments and attitudes, I'm surprised someone hasn't asked Bipto when he stopped beating his wife.
Why not take the information he's been so kind to divulge and be pleased about that?
A battery of bigfoot, a gaggle of gigantos, an aggregation of ape-men, a syndicate of sasquatch(I rather like this one), a band of boogers, a plethora of proto-humans, and finally, a posse of para-apes(just covering all the bases).
