half-life

herr doktor, the shipment of isotopes is here.
excellent, my boy! bring it to me!
yes doctor. it's very unstable, isn't it?
oh yes. yes. quite unstable. ha ha! in fact, this material is fissionable. very powerful! very dangerous!
I don't mean to be rude, doktor, but are you sure you know what you are doing?
of course! 1 part nuclear fuel. 1 part isotope. a touch of enriched uranium. some rare earths. . .
what are you making?
well it's not a salami sandwich, I can tell you.
yes, doktor, I see, but, if I may, what do you intend to do with this mixture?
don't you know? why, take over the world! ha ha!
I see. well, I'm taking my lunch, doktor.
good! go! go! hah!
don't take over the world til I get back, ok?
go! go!
and what was the name of your psychiatrist again?
dr. jungfrau, why?
oh, no reason.
