I have that feeling right now........
....that sinking feeling when my wife says something and I can't think of what to say, then I resort to personal attacks like "don't you think those size 4 pants are a little tight hun?"
Then I run out of the room like my life depended on it, because it does!
(beware young man, another comment like that and I shall be forced to retaliate with cheap personal attacks) !!
