"Being twins is fun and all, but only getting half a cake each for our birthday kinda sucks…" Len complained.
"Then how about instead of cutting up this cake we cut our numbers," Rin joked, pointing the knife at her throat. "If there's only one of us, each would have the whole cake."
"Does it mean if there's none of us, each would have infinite cake?" Len supported the joke taking another knife.
The twins loved a good joke just too much.
"Yay, infinite cake!" laughed Rin.
"For none of us!" laughed Len.
And they merrily sliced their own throats.
