The words "I Love You" have a monetary value of 163,424 pounds, or about $267,000, according to a survey of 1,000 British citizens. From Jezebel:
The poll, taken by an organization called BrainJuicer, determined the monetary value of certain phrases by first asking Brits to discuss "the happiness inspired by 'significant life events'" and then comparing the happiness attached to said events with the levels of happiness connected to recent lottery winners
Though it sounds a little shady, we did find out that saying "I Love You" is worth significantly more, monetary at least, than "making love" (£105,210) and "going on a holiday (£91,759) and is even worth more than "being in a stable relationship" (£154,849).
