Could do with a laugh today
Here's mine...
1 - I thought a filet mignon was something presented on fire, you know with brandy or something...a flamin yon 
2 - I thought rollmops where called roll 'em ups because they're rolled up but I was kind of right with that one.
Not hilarious, though dh did laugh at me til he was nearly sick, but I'm hoping some of you have much better, more embarrassing ones.
