Oh, he gets hooked up on numbers like that all the time. For a long while he thought the biggest number that existed was 54. I'll never know why.

I've got an explanation for 169 though. We're Spanish. 60 ("Sesenta") and 70 ("Setenta") are pronounced very similarly. He can handle it the first time, but when he reaches the first hundred he starts getting tired. There's a point around 169 where the 6 becomes a 7 and the 7 becomes a 6 again, and he loses track of the number he's in.

He'll get there eventually, in the meantime it is fun to watch him try :)
