What is the Truth?

"The whole Truth, and nothing but the Truth..."
"You can't handle the Truth!"
"Truth is stranger than fiction."
"Truth-or-Dare"
"The Truth. It's out there."
"...and the Truth shall set you free."
"Truth is relative."
"I am the way, the Truth, and the Life."
"There is no absolute Truth."

You'd think I'd stop asking...but I truly doubt I ever will.
