Two heads: Better than one?
It is often said that two heads are better than one. I, however, am unsure if this is true. A second head would get in the way. (Just ask Zaphod Beeblebrox.) You'd forever be arguing with yourself and obstructing your own field of vision. What rubbish. Plus, wearing hats would be awkward. You'd need two of the same hat - one for each head - and then you'd be plagued by worries that you'd look ridiculous. Also, haircuts would be twice as expensive.
That said, biheadedness would have advantages. You'd be a supreme multitasker. You could play a trumpet with one head and a baritone with the other. You could read and watch TV at the same time. You could examine your own bald spots, and determine whether or not that comb-over actually looks good. The question is: do the benefits outweigh the obvious problems?
Three heads, however, is right out. Seriously.
I mean, really?
