No, the ceiling fungus keeps dripping into my milk.

No, I'm tired of losing food fights.

No, because when I don't eat my broccoli the cafeteria lady puts me in a headlock.

No, the last time I ate the pudding it chipped my tooth.

No, I don't have life insurance.

No, my horoscope warned me not to take big chances today.

No, I'm not too fond of toxic waste.

No, I don't like to eat things older than myself.
