A New Yorker decides to have a Halloween party and invites lots of people, telling them to bring their friends. On the invitation he puts,

"Theme party - come as a human emotion."

On the night of the party the first guest arrives and he opens the door to see a guy covered in green paint with the letters N and V painted on his chest. He says to this guy "Wow, great outfit, what emotion are you?" and the guy says, "I'm green with envy." The host replies, "Great, 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, amazing outfit, what emotion are you?" 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 a guy standing there without a shirt, shoes, or socks. the host looks confused...... asked the man, "what are you supposed to be?"
The man replied, "premature ejaculation..... I just came in my pants".
