Can someone give me a riddle that is not on yahoo also is a great one plz?I'm a bit angry i need to think;)

the were 3 preist going on a pilgramage. They stop at an INN and the ask the clerk if they have any rooms avalable. the clerk says yes I have one room, but it will cost you $30. So all 3 of them split the bill $10 dollars each. so the 3 preist go up to their room to rest. When the clerk forgot that the priest get a $5 discount so the clerk gives the bell boy $5 dollars and tells him to go up and give the priest their change back. while the bell boy was trying to figure out how to split the $5 amongst 3 people he just stuck $2 in his pocket. so he gives all the preist $1 each. so if you do the math the all 3 priests payed $9 each right... well 9x3=27+2 that the bell boy put in his pocket = 29. were did the other dollar go.
