If you love me, avoid bottles and gifts of fire.

A measuring cup, piano, and most fish have this in common.

Long LIVE the legendary lock, lest a little LAUGH loses luster, leaving lessons learned and loneliness, lessening life’s light. Overtly optimistic ode, open, overall oath over other opportunities. Vicious, vivid, vibrant. Valiantly viewed. Vessel in a vice. Eternal, essential, evolves to entice. Entrancing every entity, even after a life.

I'm a newfangled whosie whatsit like a thingy detector, If you're stumped, go go and ask a certain inspector.

From round to long, I change my shape, one of me’s known for a missing escape. I sweeten the morning, lure kids from their beds, their feet find the table before sleep leaves their heads. With coffee or juice or tea I agree, always delicious, ask Homer, ask me. So what am I called, with flavors still growing, a treat much beloved and forever worth knowing?
