What The Hell?!? Friday - Testy, Swagering Rodent Edition

I have an optical mouse with my lap top, but the old relic desk top in the office has a mechanical mouse with that essential tracking item commonly called a "mouse ball."  That is not what this is about.

On measuring the males, they found that the testicles of the yogurt consumers were about 5 percent heavier than those of mice fed typical diets alone and around 15 percent heavier than those of junk-eating males.

If you ever needed a reason to eat yogurt - well, here you have it.

 Now - what are you - a man or a mouse?

H/T to Tux.
