For me, it was a couple of days ago. We recently adopted a new dog. I was rubbing his belly and noticed a small skin formation and the following dialog developed: Me: This dog is really old... it has a lot of warts, like this one. My wife (after taking a look): That's not a wart, that's a nipple. Me: That's absurd, this dog is male. My wife: Well, you also have nipples... Me: That I do... :blushing: :lmao: Now I find my self wondering if other male mammals have nipples... lions? Elephants? Please someone make it stop!
