We will never be 100

Carl was playing with my calculator, trying to work out the added age of all the members of the family. The result was 99, so I said to him: when will we be 100 then, and we realized that the next birthday is the twins, so we will never be 100.

(Of course, if you want to be picky, you could say that we already have turned 100, from a non-Euclidian point of view, or that we will be 100 between 11:49 and 11:51 on the day)
