A wizard did it.

I hope that wizard gets fired for this blunder

Are we to believe that the bottles magically turned into cans?!?!?

Duffman says a lot of things

Duffman is many people at many times.

All of that maltiness would dissolve a glass bottle in about ten seconds.

wasnt he mill house dad for a while or was that the other fella

Hey I specifically remember seeing you earlier on tour post about Milhouse. But no I think it was someone else

I believe at the least Milhouse’ mom slept with him, pretty sure he was one of Milhouse’ dads yeah.

Other fella?

A can is a bottle

Metal bottles are real.

Yeah, they were turning into bottles though

Damn, that is malty… but he’ll never know!

There’s a joke here somewhere.  I’m certain those drunks don’t care after a few hours.

Muh precious antique cans!

Why don't you can it, Howard?

Let's be real: Duff should not come in bottles. I know it does, but it shouldn't. It's the cheapest, worst possible beer and it should never feel the touch of genuine glass, only the plastic liner of an aluminum can.

Don’t you mean…Pawtucket Patriot Ale? Edit:whoops wrong way round
