Joke : I can't think of a single thing to say!
1. How can you tell if an elephant's been to your birthday party? Look for his footprints in the ice cream.
2. How does Moby Dick celebrate his birthday? He has a whale of a party!
3. How old were you on your last birthday? Eight. And how old will you be on your next birthday? Ten. Oh, I don't think that's possible. Oh, yes it is - I'm nine today.
4. I forgot my brother's birthday last month. What did he say? Rick: Nothing, yet.
5. I'd like to say something nice about you as it's your birthday. Why don't you? Because I can't think of a single thing to say!
