Random Sequence: lunes

"I dare be sworn
These dangerous unsafe lunes i' the king,
beshrew them!
He must be told on't, and he shall: the office
Becomes a woman best; I'll take't upon me:
If I prove honey-mouth'd let my tongue blister
And never to my red-look'd anger be
The trumpet any more."
--William Shakespeare, The Winter's Tale

lunes (noun) = fits of lunacy; crazyness

I suppose you could say that loons are loony-tunes and subject to lunes.
