When planning on spending all of Monday on your hands and knees planting bulbs in the garden, and you're still sore from pulling sod and prepping the soil on Friday, DO NOT start Monday off by masturbating. In addition, after spending all day Monday on your hands and knees planting bulbs in the garden DO NOT use the detachable shower-massager to masturbate again Monday afternoon.
There will be painful, painful consequences on Tuesday.
