Bathing Seán while Ríona is around always results in the following conversation, although tonight it got a bit surreal. "chin chin" is Japanese (and maybe Chinese) for "penis" by the way.
Ríona: [seeing Seán naked] chin chin! chin chin!
Dad: yes, baba's chin chin
Ríona: My chin chin?
Dad: no, you don't have a chin chin
Ríona: my chin chin all gone
Ríona: mamma chin chin?
Dad: no mamma has no chin chin
Ríona: Mamma chin chin all gone
Ríona: An pan man chin chin?
Dad: ehhh.. you'll have to ask mamma about that.
