Steel armour
He had a bee in his suit of armour!
The hardware store. One I came up with when I was about 10.
Pupil: I'd be too polite to mention it!
Wrap! (I came up with this when i was 8.)
It's already run out of battery.
Because it ran out of cluck!
A drip dry elephant!
I need space.
When you're right the whole room shouts "Here, here!" But when you're wrong one person pats you on the back and says "There, there."
Babe, it's a valve!
Make him run a lap then do 10 push-ups and sit-ups
Those who understand binary and those who don't
Boo Bees!
A zomBEE!
Mercy!
All in, du thyme
