Trouble Maker Tutu's

Three mischievous tutu's were sitting on a bench outside Wong's nursing home, when an old Grandpa wen walk by. One of da tutu's had yell out to da Grandpa saying, "A! we bet we can tell exactly how old you are." 

The old man said, "There is no way you can guess it, you old fools." 

One of the tutu's said back, "Of course we can! - Just drop your pants and bibadees and we can tell your exact age." 

Embarrassed just a little, but anxious to prove they couldn't do it, he dropped his bibadees. 

The tutu's told him to turn around a couple of times and to jump up and down several times. Then they all wen yell, "You're 87 years old!" 

Standing with his pants down around his ankles and his dingaling dingalanging, the old man said, "How da hell did you guess?" 

Slapping their knees and smiling from ear to ear, the tutu's laughingly yelled... 

"We was at your birthday party yestaday!!!"
