The young man replied, "$3.00 for you and $3.00 for  小题3:   kid who is  小题4:  than six. We let them  小题5:  free if they are six or younger. How old are they?"

Bobby replied, "Joe's three and David’s seven, so I guess I owe you $6.00."

The man at the ticket counter said, "Hey, Mister, did you just win the lottery or something? You could  小题6: yourself three dollars. You could  小题7:  told me that the older one was six; I wouldn't know the difference." Bobby replied, "Yes, that may be   小题8:  , but the kids would know the difference."
