Hedgehog Awards




MR1088326
(92c:83013) Williams,
J.
G. Combed hedgehog
kink metric in (2+1)
dimensions.
Gen. Relativity Gravitation
23
(1991),
no. 2, 181–187. Also, the famous theorem of Poincare from 1885 states that it is impossible to comb a hedgehog. Unfortunately, to the great annoyance of hedgehogs, this prominent result became known under the vulgar name of the Hairy Ball Theorem (uffa!...) so it does not qualify.

Drunken Hedgehog, Physics World, 5 (1992)
22. Apparently, the LC monitor you
are probably looking at right now can be a home to a whole
universe of hedgehogs:
Hedgehogs Radial and Hyperbolic and less orderly Metastable and Drunken ones... :)
