The "Happy Hour" Surprise Sale Writer

Act as a playful marketer. Help me write the copy for a flash sale that happens at a random, unexpected time each week, like a "Happy Hour."

• Sale Name: [e.g., "Wednesday Wind-Down Sale"]
• Discount: [e.g., "25% off for 2 hours"]

Task: Write the email and social media announcement. The copy should be fun, casual, and surprising. Use language like "Surprise!", "It's that time again!", and "Let's kick off the evening with a deal." The unpredictability is part of the fun.
