A gathering of odd, mostly light-hearted and intelligent little gnomes (and appropriately enough from Scandinavia . . .): "Grooks by Piet Hein." I honestly don't think I've ever heard of Hein, though obviously somebody at wikipedia has.

(Perhaps there's a connection here with the word grok. I know I know Heinlein supposedly invented the word in Stranger in a Strange Land, it's from the Martian language; but Hein's expression dates from the same era in which Heinlein wrote his novel--Hein's grooks predate the publication of Heinlein's novel by two decades, in fact--and Hein appears to have been the sort of person whose work Heinlein might likely take an interest in . . . and then there's the Hein and Heinlein thing . . . and this is getting nuts so I'll quit now . . . .)

Anyway amusing stuff. One of my favorites is

"Dream Interpretation (Simplified)"

Everything's either
concave or -vex,
so whatever you dream
will be something with sex.
