(Disclaimer: The author takes no responsibility for immediate crushing failure of this thread)
A couple:
Two cats on a roof, which one falls off first?
The one with the lowest mew
A neutron walks into a bar, and orders a drink. He finishes and asks how much he owes. The bartender says, “for you sir, no charge” (From fallout 3)
Any more?
