I have a few to add, just found it on another forum!

WESTERN PLEASURE RIDERS: Oh, my God, someone fix that bulb, I have to
have light so that my silver and spangles all glow to their best and
so that all the highlighter on Old Peanut Head makes his nose look so
smooth and sparkly and oh, my diamond studs have to flash in the
light, you know, so oh, someone has to fix it. Oh, maybe you without
all the silver on your saddle, obviously you can't ride, you can do
it

BACKYARD HORSEMAN: Do I have to do everything??!! Oh yeah, I do, don't
I? I'll get to it as soon as I'm done mucking stalls, cleaning and
filling the troughs, cleaning and filling the water buckets, stacking
my hay, setting up for night feeding, cleaning my tack, picking out
manure from the paddock, brushing and exercising the horses, and
whatever else needs to be done.

HUNTER RIDER: Well, I'm waiting for my trainer to tell me exactly how
but he's changing light bulbs somewhere else right now.
