A four horse day - A four horse day can also be when you have so much free time

A four horse day can also be when you have so much free time you start thinking about riding horses, even though you're not a fancy rider.

I had a four horse day and ended up riding my neighbor’s horse just to prove a point.

I said, 'Today is a four horse day!' My friend said, 'You're just trying to avoid doing laundry.'

I had a four horse day and took a nap so long, my dog started snoring with me.
