has started to refer to my hoya ellipticas as "the street pizza hoyas".

For those who may not get the joke, down in the South, it is quite common to run across a flattened animal or three on your journey home. Included in the list of fatalites, are turtles. Flattened turtles. Street pizza. Ugh. Horrible sense of humor, but I will grudgingly admit, he has a point...

I guess it is no worse than "ironed tortoises"...
