When I was in school, I used to ask a lot of questions. One day I asked Ms. Doris, our English teacher, "Why do we ignore some letters 'H' like in hour, honest, honor, etc?"

Ms. Doris replied, "We are not ignoring them. They are considered silent."

During the lunch break, Ms. Doris gave me her packed lunch & asked me to heat it in the cafeteria. I ate all the food and returned her an empty container.

Ms. Doris asked me, "What happened? I told you to go and HEAT my food & you are returning me an empty container?"

"I'm sorry, Ms. Doris, I thought the 'H' was silent."

Why do humming birds hum?

Because they forgot the words.

Why did the girl spread peanut butter on the road?

To go with the traffic jam!

Grandson: But these are the only feet I have?

Grandfather: Fair enough.
