I dont get it. 3rd gender?? First  you are either male or female and then you are either gay or straight. Where does this  3rd gender come from? Either you have penis or vagina? Doesn't matter its 6 inch penis or 1 inch,  its still a penis. Either you have vagina with enlarged clitoris or no clitoris, its still vagina. So why 3rd gender??What are the criteria for 3rd gender?
If there is really such things like 3rd gender, then it should be Nepali politicians. Tag them as 3rd gender. I am up for it.

You are a third gender when the following criterias are met

• you have the first gender that is protuding from your body
• you have the second gender that is able to encapsulate the protuding organ of the first gender
• the first gender is permanently fitted inside the second gender
• the combination thereof is known as the third gender

First and 2nd sentence make sense but 3rd and 4th not much.

Don't you hate it when noone gets your joke but you can laugh about it because you do get it? The Irony.

ha ha... May be they get my jokes down the road. You know the story about the gainda. Gainda lai kaukauti layo pani ek kosh para gayera haschcha ;) May be I am that gainda right now regarding the 3rd gender. Somebody show me the anatomy of 3rd gender: combination of 1st & 2nd gender. I have watched shemales though Lol. Is that what it is? But they dont have penis & vagina stuck together.

It's supposed to be a joke, are you expecting it to be true? 

I take offense on the order you have chosen. Why is female gender the second? Why are Trans the third, not the first?

Third gender =
Hirajs of India
Ladyboys of Thailand
Fa'afafines of Somoa

The third gender in many cultures are people who are born anatomically male but they go on to take a feminine gender or sexual role. Imagine a guy who took on a feminine gender/sexual role but he did not have a sex reassignment surgery and sleeps with masculine males. So is the person a he or she? It is confusing, right? Maybe this is why they are known as the third gender.
