That's funny...that's the exact same line my mom gives me.
to mother, after she kept asking:
me: "i dunno, i think i won $450 today or something."
her: "but how much did you lose??"
OH man, i HATE this one the most. The question confuses me and I don't understand what the hell is going on in their confused little minds:
friend: "how much did you make today?"
me: "about $450"
friend: "yea, but did you lose any?????"
me: "uhh...what? I said I made about $450. NET."
friend: "yea, but did you LOSE any!??!?!"
me: "I don't get the question. I said I netted $450, wtf?"
friend: he must have lost a lot...poor guy. too bad he can't play like I did at our last home game. I always hit that third seven.
