Need some wood? 

Definition:
Question usually posed to an ass clown at a point in a conversation or relationship where the ass clown has grossly exceeded the limits of patience and tolerance in others who were, up until that point, making every effort to engage the ass clown in a civil discussion or relationship and indicating that the ass clown now runs the risk of unleashing a wrath previously withheld. The target of such a question is being informed that they have descended into such utter stupidity that their only possible hope of salvation is the application of a hard piece of a tree to the side of their head (for starters.) The phrase is stated rather than asked to indicate that the ass clown may be in imminent physical peril. Usage of this phrase is similar to bam stick although usually in a calmer tone - such as the phrase "You asked for it."
Background:
Asked, as if joking, by President George W. Bush of Senator John Kerry during the second 2004 presidential debate at a point where Bush knew a recent reference to timber would confuse his adversaries.

You WRECKED my car AGAIN? Do you need some wood?

BUSH: I own a timber company?
(LAUGHTER)

(LAUGHTER)
