In reply to Stewpot:
Remember the Wrangler adverts, "Mr Wrangler needs you!"*, featuring a Lord Kitchener-style figure pointing at you, the viewer? Well I'll swear that I once saw him wink at me. Mind you, I had earlier that evening consumed a particular type of mushroom. Just the one though, and I was told many more would have been needed to produce a noticeable effect.
