Reminds me of a riddle I heard in high school (around the time Canada switched to metric): If it's 0 Celsius here, and twice as cold in Ottawa, what's the temperature there?

Conflating both the #ZeroIsNotMinimum problem and a negatively worded question about positive values.

Think of "If it's 273 Kelvin here, and twice as cold in Ottawa"... would that be 546 Kelvin in Ottawa, or 136.5 Kelvin?
