Manlocks, roused from slumber, and ever cautious, moves carefully through the microvilli of the Tubuli Recti and Rete Testis, taking the opportunity, from cell to cell, to hide behind each palm-tree like, waving flagellum, careful not to get hit by any wayward coconuts that might be around. With increasing care, he jumps from hill to valley to hill to valley of the treacherous, ankle-breakingly irregular ductuli efferentes before converging on, finally! The cover of the branching stereocilia of the ductus epidydimus.

Yup, it's histology time, again!!!!!
