"I will do anything to pass" joke

A student comes to a young professor`s office hours. She glances down the hall, closes his door, kneels pleadingly.

"I would do anything to pass this exam." She leans closer to him, flips back her hair, gazes meaningfully into his eyes. "I mean..." she whispers, "... I would do... anything."

He returns her gaze. "Anything?"

"Anything."

His voice softens. "Anything??"

"Absolutely anything."

His voice turns to a whisper. "Would you... study?"
