The case of the mysterious shirt circles

The mystery: several of Job's shirts suddenly had a large, identical round stain on them, mid torso. No clues as to how these stains came about. They seemed to appear overnight. Like crop circles....

and they were driving us crazy!

Many moons later....

Job arrived in the living room one morning with a bottle of spray oil in his hand, and a sheepish grin on his face. He had solved the mystery.
Turns out as he was cooking breakfast for us lately, he propped the can of oil on this chest to take off the lid, leaving a nice circular stain of oil on several shirts.

Thank goodness for Shout and a sense of humor. We thought this little mystery was quite amusing ;)
