Snowed-In Whistleblower

Listen up, buttercup! This joke is playing on the double meaning of "snowed in." One meaning is that a person is physically trapped in their house because of heavy snowfall. The other, more cunning meaning, is that a "whistleblower" is a person who exposes the wrongdoings of an organization. You get it? The whistleblower is covered in snow, which also represents all the dirt he has on an organization. It is like being stuck in the dirt.
