Bedroom wrong name snafu, is there any save you can do?

We have all just about seen it on TV or in the movies the guy/girl in the throes of passion calls out the wrong name in bed (I have only heard of it happening to one man and it was not me), but if it ever happened in life is there really any come back or save for that one? Do you grab your toothbrush and pack your bags, grovel for forgiveness, lie, anything?
