It seems fractured, but I think
My Latin sig is criminal because I think stupid people are sane and clever.

Quote from Horace, the full version of more common "carpe diem".

My hovercraft is full of eels (again).

Translation by Google:
"The more corrupt the state is then the more numerous the laws." -- Tacitus, The Annals of Imperial Rome.

This may be a Libertarian/Conservative catch-phrase.

Here

Thus the biscuit crumbles.

Navicula hydraulica plena anguilarum est. Omnes castelli tuus nostri sunt. Ed elli avea del cul fatto trombetta.

"Navicula hydraulica plena anguilarum est" = "the hovercraft is full of eels".
"Omnes castelli tuus nostri sunt" = "all your base are belong to us".
"Ed elli avea del cul fatto trombetta" = ?
"Words" doesn't recognize enough of this that I suspect it is not Latin.
Confirmed by websearch: It is Dante making a fart joke.

See "Sed quis debugget ipsos debugator?" a few entries ago. (Which is correct?)

Minutus cantorum, minutus balorum, minutus carborata descendum pantorum

Translation found by google:
"A little song, a little dance, a little seltzer down your pants."

here.

The first phrase is famous and googlable.
"Thus passes the glory of the world; not with applause, but with bad Latin."

Presumably "Who will debug the debugger?"

Orationem pulchram non habens, scribo ista linea in lingua Latina

And translation via Google:
"Lacking anything witty to say, instead I offer this tagline in Latin"

Translation by Google:
"If I were you, I wouldn't walk in front of any catapults."

Two quotes in one .sig here

Translation by Google:
"Armis Exposcere Pacem" = "They demand peace through force of arms." (A similar sentiment to "Ubi solitudinem faciunt, pacem appellant".)

"Scientia non habet inimicum nisp ignorantem" = "Science has no enemies but the ignorant."

From here.

Translation is "They condemn because they do not understand."

From here.

What Words says

Google says: "I think some people in togas are plotting against me." (Where does "I think" come from?) It is another of the humerous Latin phrasebook quotes.
