Funny Joke

Once Cleopatra called all the Great men of history in a single room- Lincoln, Lenin, Gandhi, Martin Luther King etc..,
Cleopatra: If a man in this room does not have a erection, when i put on my bikini, then i will take that man to my room and satisfy him.
*Cleopatra puts on bikini and everyone has an erection except Gandhi*
So Cleopatra takes Gandhi to her room, and takes off all her clothes, still Gandhi does not have an erection, angry, Cleopatra banishes Gandhi out of her room.
The next day.
Lincoln:How can you resist such temptation?
Gandhi:I can't
Martin Luther King: But what about yesterday?
Gandhi:Today i just realized that i wasn't wearing my glasses yesterday..
