Antidote to gloom

I seem to be surrounded by GLOOM. Gloom is everywhere, global gloom, then there is autumnal gloom and something called SAD which comes with Christmas. So, I say, lighten up a bit, take precautionary measures to counteract gloom. I recommend any activity, provided it is done badly, strive for incompetence and above all read nonsense verse thus:

There was an old person whose habits
Induced him to feed upon rabbits;
When he'd eaten eighten,
He turned amazingly green,
And thus he relinquished those habits.
