I went to go mine for some gold, but then I saw some shorts.

Friend: "Your jokes are too short."

Me: "Zip it, my jokes are always golden."

Friend: "You're such an ingot, don't forget your jokes are always Aurum."

Me: "I know my jokes are Aurum; it's always because I always glitz."

Friend: "At least I have luminescent" (Get it? Lu mines cent)
