Not recently, it's cold outside.
When I had a garden, I'd pee in it if I was doing yard work and nature called (not out in the open though). Healthy human urine is rich in nitrogen, phosphorus, and potassium. Plants like that stuff. You don't just concentrate it on a single plant. Wave it around to spread the wealth.
I've been known to make yellow snow too in trying to sign my name but usually don't have enough to get past my first name (a downside of having a last name with 14 letters in it).
