beware of Greeks bearing gifts

fadi99

Can be best described as never let your guard down.

Origin:
Those of you who have seen \"Troy\" the movie should remember
the story of the Trojan Horse... Which is indeed a gift from
the Greeks. So... beware of Greeks giving you a gift! It may
not be good for you!


Variations
With the computer age, this saying is sometimes transformed
into \"beware of geeks bearing gifts\", usually used by anti-virus
companies.


Closest Chinese Equivalent Saying
Hmmm... Any one? I wouldn't use \"knife hidden in laughter\" since
that implies lying. This saying is merely advocating caution.
