You can't get high from LSD by touching it. Albert is a liar. He nibbled some. My theory is, he knew those in the know know that this is an impossible way to get high, which is why he stuck with it (a crafty wink). He could have simply said he got a little on his finger and touched his mouth, but he stuck with the skin absorption story. Just a little harmless tinfoil.
It reminds me of one of the early anatomists–Leonardo da Vinci, maybe? They found the cause of one of the leading causes of death at the time: appendicitis. In their publication, they invented a story about an ailing soldier being killed in such a way that the inflamed appendix was exposed. It was a lie, and a rather obvious one. But it was necessary because dissection was forbidden at the time.
