Funny Blonde Joke

There was a blonde who found herself sitting next to a lawyer on a airplane. The lawyer just kept bugging the blonde wanting her to play a game of intelligence. Finally, the lawyer offered her 10-1 odds, & said everytime the blonde could not answer his questions she owed him $5, but everytime he could not answer hers he'd give her $50. The lawyer figured he could not lose & the blonde reluctantly accepted. The lawyer first asked, "What is the distance between the earth & the nearest star?" Without saying a word,the blonde handed him $5. Then the blonde asked, "What goes up a hill with 3 legs & comes down with 4 legs?" Well, the lawyer looked puzzled. He took several hours, even looking up everything he could on his laptop & even placing air-to-ground phone calls trying to find the an answer. Finally, angry & frustrated, he gave up & paid the blonde $50. The blonde put the $50 in her purse without comment, but the lawyer insisted, "So, what was the answer?" Without saying a word, the blonde handed him $5.
