Here are 5 jokes:
-
Why don't scientists trust atoms? Because they make up everything.
-
What do you call a fish without eyes? A fsh.
-
Why did the scarecrow win an award? Because he was outstanding in his field.
-
I told my wife she was drawing her eyebrows too high. She looked surprised.

What do you call a bear with no teeth? A gummy bear.
