This reminds me of an old Doonesbury cartoon. Two Congressmen are sitting listening to Nixon's lawyers.

"'No impeachable offense. No impeachable offense' mimics one. "How can St. John keep spouting that gibberish?"
They lapse into a despondent silence.
"If only" says the other "he'd knock over a bank or something."
"By George!" shouts the first "We'd have him then!"
