LECTURE 73

419. [Lichen 419] Lichen verna L. Ordinary stone-lichen, blooms May-June
420. [Lichen 420] Lichen norwegicus L. Norwegian field-lichen, grows only on old norwegian thing places or old manuscripts. Singular communication system, based on runes. A similair species, Lichen greenlandicus L. can be found on Greenland, Lichen erica L. can be found in Conny Islands.
421. [Lichen 421] Lichen argentus Brook. Found mostly on the wallstreet, earns its living by speculations on fund-bond-derivates (?). Lichen argentus tie Brook. wears a tie, Lichen argentus untie Keynes not. Can be used to forsee the future, increases inflation, decreases deflation.
422. [Lichen 422] Lichen polyvalentus L. Grows on seldom used pavements, sometimes also on sidewalks (??). Can be boiled and used to cook delicious meals with heavy side-effects (happyness, sudden death, fear in the dark, third eye, spititual knowledge). Forbidden in certain contries.
423. [Lichen 423] Lichen lichen Linné. Interesting reproduction cycle. But since it's rather naughty, I wont tell you anything about it.
424. [Lichen 424] Lichen larix Löffelst. Grows on TV channels. There it infiltrates certain series, mostly sit-coms, than takes over the whole network, forces the channel to broadcast mainly programms related to lichen, then infects the unsuspecting viewer who serves as a zwischenwirt. A subspecies, Lichen larix libri Löffelst., is said to grow in books, mainly in adult education prospects, where it changes the content of the books to lichen-related things. Whole lectures become worthless if infected with this lichen.
