I picked up a chef's knife that was 99% identical to one I have, but beaten up from being in the road.

TLC with a stone would fix it, but I was first thinking of pranking my kids with it on April fools' day. However, this doesn't seem particularly very funny.

One year I told them that there was a fire at our local Walmart and that all the partially burnt and melted Lego sets were on sale for $0.10 each. I showed them Google pictures of Walmart fires. All Walmarts look the same, so they bought it hook, line, and sinker.
