about 4 or 5 years ago I brewed Memory Lapse Pale Ale. I think I modified with a different hop, can't remember.
At any rate, i had several buddies over to try and kill the keg and to pay them (in beer) for helping me move out an ex-girlfriend. They kept killing those beers. In fact, around 10pm I told them I was going to bed and they kept drinking till midnight.
A few weeks later I started hearing the stories. One buddy said he had to pull over at the bottom of the road because he was too drunk to drive, another buddy said he had crazy dreams about gigantic spiders that were encrusted in gems (apparently he woke up talking about them and it freaked his wife out because he was talking about killing it), then the other buddy just said that he couldn't believe how drunk he got on that "easy drinking beer."
To this day they ask me when i'm going to brew that "psychedelic beer" again. Or if I offer them beer, they always ask if it will make them go crazy like that last homebrew.
