Sceptical Puns

But I'm not buying it.

Soo.. a little background: my mother was about to visit for a walk outside the next day when this dialogue happened; also: my native language is german and i don't know if this very common in english as well, but my daughter calls my mother <stgm_at's-mother-first-name>-gramma. for the sake of this post let's assume her name is elizabeth.

so here goes...

(i enter the living room; wife & daughter sitting on the couch)

daughter: (in a moderately excited voice) hey dad, you know who's going to visit us tomorrow?

me: (acting as if i didn't know) don't know, who?

daughter: elizabeth-gramma.

me: huh, really, but do you know who is also going to visit us?

(daughter looks at me even more excited, there was defenitely a twinkle in her eye; wife looks at me sceptical)

daughter: don't know, who?

me: my mum.

(cue rolling eyes and groan from my wife and laughter from my daughter)
