Sometimes more is more. Two chubby chappies for the price of one. Lovely. Two Snakes of Tindalos. Groovy! Two Bulky Ancestors… well, that’s beyond spiffingness, innit. As to hypothetical doubles...just imagine: two Vladimir Putins (not ideal strictly speaking but, boy, would that annoy all the bien pensants and all the pious bovines out there!). Stay cool and sane.
