There was this former neighbour: Siren Kid.
His apparent calling in life was to run from his house to the bottom of his garden, whilst doing the best impression of an emergency vehicle that his young vocal chords and lungs could muster - There have been foghorns with less volume than he. Upon reaching his destination, he would immediately RTB, still on blues and twos.

Safely back on station, he'd immediately dispatch himself onto the next of that days many, many emergency calls; and so it would go on, more "woo"s than a month of b3ta, until what seemed like days later (but couldn't have been more than a few hours), his shift would be over and he'd go back inside - Presumably to go have a nap, and play as Make Ready Kid*.

* A service whereby non-medical staff (are meant to) clean and resupply ambulances between shifts, freeing proper medical staff to attend calls their whole shift.
