That does sound like fun! I remember the day I weighed myself holding my vacuum cleaner! It weighed 45 pounds, exactly the amount I'd lost. Next on my list is taking a picture of me standing on the scale with my son, but darnit, the kid keeps moving my target! (He won't stop growing!) He's 89 pounds now so I have a ways yet to go. I hope he doesn't get past 100 before I reach my goal. I'll have to go hunt down someone else's kid.
I like this idea!
Another thing I did, and posted around here, was take pictures of myself in size 10 jeans when I was still wearing 18's.
I took progressive pictures of me getting into them. Kind of fun.
