I'm such a nerd. I heard this joke and laughed my a$$ off.
two neutrons walking down the street
one turns to the other and says "i think i just lost an electron"
the other says "are you sure?"
the first replies "yeh i'm positive"
And here's another dumb joke for you while I'm at it.
Mahatma Gandhi, as you know, walked barefoot most of the time, which produced an impressive set of calluses on his feet. He also ate very little, which made him rather frail and with his odd diet, he suffered from bad breath.
This made him. .... A super-calloused fragile mystic hexed by halitosis.
For those of you who've seen my show, you'll understand why I like that joke.
