Golden Spleens

In 4539 George and Neal decided to dabble in alchemy and turned themselves into golden statues. Luckily the effects were only temporary and by 5935 they were restored to their normal selves. Except for their spleens, which went on to have songs and limericks written about them, like:

There once was a spleen I've been told, 

Around for so long it was old, 

This spleen could not rupture, 

For its atomic structure, 

Had been changed from carbon to gold.
