以下，各附上例句來詳細解說。
A few cards short of a full deck.（愚蠢 / 少根筋）
He is a few cards short of a full deck.
他有點愚蠢。
deck是一副撲克牌的意思。
一副撲克牌共有52張牌。這句英語俚語利用「少了幾張牌」，來比喻某人「少根筋」、「愚蠢」的意思。
A few sandwiches short of a picnic.（愚蠢 / 少根筋）
Ken is a few sandwiches short of a picnic. He quit his job to live in a caravan.
肯真的很愚蠢。他為了生活在露營車裡而辭掉工作。
Mary always makes mistakes. I think she is not 100%.
瑪麗總是犯錯。我覺得她有點少根筋。
這句俚語的英語直譯是「她不是100%」，比喻她「少根筋」、「愚蠢」的意思。
Not playing with a full deck（愚蠢 / 不明智）
Jimmy’s not playing with a full deck if he thinks he can fly without wings.
如果吉米認為他沒有翅膀也能飛，那他真的很愚蠢。
這個俚語與剛剛介紹的「A few cards short of a full deck」類似。直譯為「玩一副不完整的撲克牌」，比喻某人「不明智」、「愚蠢」的意思。
Not the sharpest knife in the drawer.（不聰明 / 笨拙）
Dan is not the sharpest knife in the drawer, but he is pretty good-looking.
丹不太聰明，但他長得很好看。
「Drawer」指「抽屜」。「sharpest」是「sharp」的最高級，有「最鋒利的」的意思。
因此，這句俚語的英語直譯是「不是抽屜裡最鋒利的刀」，比喻某人「不是最聰明」、「有點笨拙」的意思。
Not the brightest star in the sky（ 不聰明 / 笨拙）
I like Jane but I don’t want to work with her on a group project. She is a hard worker but she’s not the brightest star in the sky.
我喜歡珍，但不想和她一起做小組項目。她很努力，但她有點不聰明。
