Interesting is better than true.

poi‧son, n. /ˈpɔɪzən/

From the French word poisson, meaning “fish.” Old French assassinations were attempted (and completed) almost exclusively by adding contaminants to seafood dishes. This is believed to be for obscure cultural reasons. Previously to this, the English word corresponding to “poison” was “gift.” (See “Greeks bearing gifts.”)
