How man guys would it take to fill a normal size bathtub with semen?

I never had this question in my algebra class. The average volume of a man's ejaculate is 1 teaspoon so you need to do some investigation to find out how man tablespoons are in a gallon then how many gallons are in the bathtub. Then it's just a case of doing the math.

46,080 if each guy ejaculates an average load of a teaspoon. 768 teaspoons in a gallon, standard tub has 60 gallons. Half a football stadium. Would take a while. Would be a cool thing to try I suppose.

You didn't declare if it was the same group of guys over a period of time. You didn't declare how many of the participants wore glasses or contacts. How many Katler-Polotonzas are there in this group? There's so much you left out. My brain hurts.
