A little humour goes a long way

My six year old daughter told me some jokes this morning as I got ready for work. Here are couple that made me smile:
What goes ha ha plop?
- A man laughing his head off
What do you call underwear thieves?
- Nickers
What do you call the boss of a tissue factory?
- The hankie chief
I don't know about you but I think a bit of silliness starts the day pretty well...
