Noah was standing at the gangplank checking off the pairs of animals when he saw three camels trying to get on board. 

"Wait a minute!" he said. "Two each is the limit. One of you will have to stay behind." 
"It won't be me," said the first camel. "I'm the camel whose back is broken by the last straw." 
"I'm the one people swallow while straining at a gnat," said the second. 
"And I am the one that shall pass through the eye of a needle sooner than a rich man shall enter heaven." said the third. 

"Well, I guess you had better all come in," said Noah, "the world is going to need all of you."
