riddle

A potato’s key tool, I have all the power.
I am generally used on the half or full hour.
If my cells were deceased or lost or the such,
My partner would only respond to your touch.

What am I?

Three brothers share a family sport
A non-stop marathon
The oldest one is fat and short
And trudges slowly on
The middle brother’s tall and slim
And keeps a steady pace
The youngest runs just like the wind
Speeding through the race
“He’s young in years, we let him run,”
The other brothers say
“‘Cause though he’s surely number one,
He’s second, in a way.”

HOW?!

Think of words ending in -GRY.

Angry and hungry are two of them.

There are only three words in the English language.

What is the third word?

The word is something that everyone uses every day.

If you have listened carefully, you already know what it is.

GJ Rob, Brian, and Will on the last one :)

PS. DON’T CHEAT!!

I can sizzle like bacon,

I am made with an egg,

I have plenty of backbone, but lack a good leg,

I peel layers like onions, but still remain whole,

I can be long, like a flagpole, yet fit in a hole.

…what am I?

and also congrats to rob for getting the first one :)
BUT NOT REALLY CUZ HE CHEATED

I’m always in charge.

I’m never in debt.

I’m known as the first amongst all my kind.

I’m found within cars,

but never in buses.

I’m not used in Mexico,

but I’m used in Palestine.

…What am I?
