We don't intend to drink two bottles of wine when we specifically said we were only going to have one glass. That I would call weak-willed.

Machiavellianism is measured by personality tests and so called 'high Machs' - those who score high on Machiavellianism - are strategic long-term planners. Lance Armstrong has become famous for his apparently altruistic work with cancer charities - this echoes Jimmy Savile's extensive similar charitable pursuits.
Of all the wonderful Olympic moments, I can't decide which to claim that I witnessed first hand. I could go for something obvious, like Mo's 5000m or Jessica Ennis wrapped in the flag.
