Mine

Excuse me, humour nazi here: whereas "Mine" is pronounced exactly like the german "Mein", "fewer" (IPA: [fyoo-er]) doesn't sound a bit like "Führer" (IPA: [ˈfyːʁɐ]). No fun detected.

Also, "mine less" could be accurate. Saying "mine less ores" is incorrect, but to say "mine less" as in to decrease the rate of mining is correct.

this joke is great;
