"Terrell's suggestion to hold Sergeant Sheila Estrada’s welcome-home celebration at a bowling alley went over like a lead balloon," said Cheryl. Terrell's suggestion is hard to comprehend because it's never been done before. Terrell's suggestion is as clever and unique as a balloon made out of lead. Terrell's suggestion sounds exciting at first but is actually empty. Terrell's suggestion would be a dismal failure as would a balloon made out of lead.
