Just one of those random questions that pop up in my head.
Jacob was tricked into marrying the 'wrong' sister, Leah.
I get that the bride was veiled, etc. But...come the actual wedding night, shouldn't he have realized he was bedding the wrong woman? I don't think she kept the veil on the whole night...
The only explanation I've seen put forth for this is that Jacob was drunk (and I mean really, really drunk - like, nine sheets to the wind drunk) by the time consummation came around. That his father in law, Laban, got him purposefully drunk so he wouldn't notice.
