The Age of Asparagus

I tend to associate mondegreens exclusively with misheard song lyrics, though not so much with whatever it was Mary's dress was doing in Bruce's Thunder Road but as it happens there are scads of non-musical instances. 

Actually, scads may be a bold-faced lie, unless it's a bald-faced one. 

Of course, it's a little hard to tell with the light in here.
