The Malfoys have always had the reputation, hinted at by their not altogether complimentary surname, of being a slippery bunch, to be found courting power and riches wherever they might be found.

“Pride goeth before destruction, and an haughty spirit before a fall.”

Lord Voldemort: How can you live with yourself, Lucius?
Lucius Malfoy: …I don’t know.

Lucius: I wasn’t that drunk last night
Narcissa: you were rolling around in the fireplace yelling “Diagon Alley” without floo powder.

I always enjoy Lucius’ snide remarks. All Malfoys are genetically disposed to make them.
