Get on the back half of that motherfucker

Embracing an unmissable opportunity such as how a Munted Gunty may feel the need to take a massive dildo all the way down to the base, i.e. the back half.

"Get on the back half of that motherfucker" said Dick Rangah when he realised that the petrol at the local servo was on special.

Or.....

Tom Cruise was so horny for some ass action that when John Travolta walked past he couldn't resist getting on the back half of that motherfucker.

the half-life decay of plutonium-239 in a zinc-aluminum material lined caging

caged plutonium which is a transuranic material that has a half-life of 24,065 years, making it decay (into different elements) inside a zinc-aluminum hull (the aluminum delicates due to the radiation and thus might crumble depending on the weight of plutonium-239) but doesn't rust as easily due to the zinc coating

"Our team have created a simulation of the half-life decay of plutonium-239 in a zinc-aluminum material lined caging scenario."
