This bloke decides to have a party and invites lots of people, telling them to bring their friends. On the invitation he puts "themed party - come as a human emotion".
On the night of the party the first guest arrives and he opens the door to see a bloke covered in green paint with the words N and V painted on his chest (in another colour). He says to this guy "Wow, great outfit, what emotion have you come as?" and the guy says, "I'm green with envy". The host replies, "Brilliant, come on in and have a drink".
A few minutes later the next guest arrives and the host opens the door to see a woman covered in a pink bodystocking with a feather boa wrapped round her most intimate parts. He says to this woman "Wow, great outfit, what emotion have you come as?" and she replies, "I'm tickled pink". The host says, "I love it, come on in and join the party".
A couple of minutes later the doorbell goes for the third time and the host opens the door to see two Irish guys, start-bollock naked, one with his penis stuck in a bowl of custard and other with his penis stuck - in a pear.
The host is really shocked and says "Christ, guys, what the hell do you think you look like, you could get arrested for standing like that out here in the street. What emotion is this supposed to be?" The first guy replies (in a strong Irish accent), "Well, I'm fucking disgusted and my friend here has come in despair."
