The satirical butchery of the German language Trevor posted called to mind a silliness we perpetrated on a client we'd come to know over years of doing work on his odd "fleet" of cars. He'd found a Mercedes 380-SL he'd just bought for his wife, who was recovering from cancer surgery, as a "pick-me-up." He brought it to us to check over and service. It was gold with the chrome "eyebrows" on the wheel arches, we joked with him about it being a bit to "flash" for her.
Before I closed the hood, I lettered a piece of duct tape with:
¡ACHTUNG!
SCHTUPPEN DER DIGITS IN DER VERKS MIT
DER MOTORKLANKEN IST VERBOTEN!
Put it on the fan shroud, forgot about it until a month or so later when he called, laughing hysterically over it. He'd decided to check the oil level. Said it was the best laugh he'd had in months.
