In reply to John Rushby:
Dunno about keeping squirrels as pets, but I once knew some blokes who used to enjoy going for picnics in Hyde Park on sunny Sundays. Nothing unusual in that.
They also enjoyed puffing on a few joints along with their picnic... Again, hardly revolutionary.
They took things further by taking along bunches of grapes, that they'd previously injected with vodka, and then proceeded to feed them to the park's resident squirrel population.
The combination of stoners and drunk squirrels was a potent one, with the former incapacitated with laughter as intoxicated tree-rats fell out of branches, ran into tree trunks, fell over their own tails etc. etc..... It takes all sorts, I suppose?
