One that's making the rounds of various usenet humour newsgroups:

"CORPUS CHRISTI" is, as most know, old Latin for "Body of Christ". We have
received a list of new Latin phrases, "ex quo" (from which):
a.. "Domino vobiscum!" (The Pizza guy is here.)
b.. "Revelare Pecunia!" (Show me the money!)
c.. "Motorolus interruptus." (Hold on, I'm going into a tunnel.)
d.. "Sic semper tyrannus." (Your dinosaur is alway ill.)
e.. "Bodicus mutilatus, unemploymi ad infinitum" (Better take the nose
ring out before the job interview)
f.. "Nucleo predicus dispella conducticus" (Remove foil before
microwaving)
g.. "Veni, vidi, velcro" (I came, I saw, I stuck around.)
h.. "Et tu, pluribus unum?" (Did the government just stab me in the
back?.)
i.. I also received a sweat shirt for Christmas scripted with this
announcement on its front: "SI HOC LEGERE SCIS NIMIUM ERUDTIONIS HABES" (If
you can read this, you have too much education)
