LOL!

2yos don't usually understand puns, let alone make them. Think about all that's involved in a pun, the complex understanding of language and translating that into humor. There's a reason puns are my favorite form of humor. People who say they are lowly lack imagination and a love of language.

My bet: your DS is GT. How GT, it's too soon to say. But he's clicking faster than ND.

And long live the pun! grin
