How to gain 30 lbs

Just after Xmas, the boss decided that our weight loss plan would be helped by getting a Weight Watchers scale. 
It's fancy, it'll measure your fat, your BMI, and probably some other things if you'd let it.
Yesterday, I was dumbfounded when it told me I'd gained 5 lbs since the day before. This morning, it told me that I'd gained 25lbs since yesterday. (That's when I considered that the nutrition info on the packet of chocolate digestives I'd devoured was all to cock.)
Some investigation and a phone call to the store told me that it is a POS and they would replace it without charge.

Problem is, they've replaced it with the same model.

I wonder....


Ah well...
