As Don mentioned, first check is the oil dipstick; both to check for overfull and the condition (contamination) of the oil.
It is certainly possible for carburetors to pour in so much fuel that one washes down the rings, and fills the crankcase with fuel; HOWEVER, if this is the case, your wife would have been unable to see you for the black smoke!
My guess would be something else, as mentioned by Jerry.
