First joke

Rach doesn't believe I made this up, but it's true - Ollie even thought it was funny! Warning though: if a 5-month-old thinks it's funny, it's probably only the blokes among you who will as well...

I just had Ollie on my knee this morning and he was enjoying the knocking noises I was making with my tongue. Hence the joke that follows:
Knock knock.
Who's there?
Oliver.
Oliver who?
Oliver cross the street, and just thought I'd come and say hello.

Cue laughter from the short one.

I now apologise for subjecting you to that. I still think it's kinda funny though!
