Loeki de Leeuw was a lion puppet who appeared in short advertising bumpers on Dutch public television from 1972 until 2004. Created for the STER foundation, his sketches usually ended with a small mishap or surprise, followed by his cheerful catchword Asjemenou, a playful contraction meaning roughly well, would you believe it. The bumpers became part of daily viewing for generations of Dutch families. Clips and references later circulated online, where the short exclamation survived as a nostalgic reaction sound beyond its original broadcast context.
