My bike is always tired because it's two-tired.

Why did the stairs always get in trouble?

Because they were always up to something!

I'm a baker, and I'm feeling crumby today.

Your mom asked me to try and fix the coffee maker this morning, because it was really slow and sputtering. I tinkered with it for a bit, but it just wouldn't cooperate.

I guess it was still trying to perk up.
