Human: Generate for me a description of a comedic scene inside a tunnel tower with stoneworkers, a cloth apron, and a worker. Assistant: 
Evidence of new construction -- fragments of chiseled stone and splinters of new wood -- lie scattered about the tunnel floor. The stone walls have been cleaned and appear to be in the process of being polished. Perhaps as a jest, some of the stoneworkers have discreetly imprinted their initials in the new mortar. A worker has left behind a small cloth apron, its hem firmly trapped in the tight joint between two wall slabs.
