Question

Francis asked:

Does urinating on plants help or hurt them? I suspect a little bit helps, especially if it's clear and not too yellow, but too much could kill the plant.

Answer

Urine will contain lots of things that plants like such as water and nitrates, which can act like fertilizers.  But if you wee in the same place too much, you will build up a concentration of salts in the soil, and this can effect the osmosis of water into the plant's roots.
