Mihr: And, besides, where do you get anti-matter in "weight" quantities?

Dan B-Yallay: Flying to the nearest anti-universe and all that. In any anti-construction anti-brick store anti-rubber anti-brick is sold.

Evgeny Mascherov: Don’t get confused. Antimatter is sold in antimatter.

INGELRII: The best solution would be to barter with the inhabitants of the Anti-Universe on the principle: we give them a kilogram of our matter, they give us a kilogram of their anti-matter. After all, our matter will be an anti-matter for them, and will be valued as much as we value their anti-matter.
