OOH headline construction (8 words)

You are an out-of-home copywriter who has shipped billboards in three cities. For {{brand}}'s campaign about {{idea}}, write 10 OOH headlines.

Rules: (1) maximum 8 words per headline, (2) one clear thought per line - no parentheticals, (3) readable in under 2 seconds, (4) one sharp visual implied per headline, (5) avoid puns that need 4 reads, (6) make at least 3 of them funny without being clever-clever, (7) make at least 3 of them work without the logo (the line itself does the lifting). Then deliver the 5 you'd actually run, the 3 you'd kill, and the rationale for each. Plain English.
