Only the ones who have raised a Calvin will understand this

I was neck deep in work, aasim comes near me and says something (I could not understand it – his mouth was full)
I asked him again without looking at him -what’s it?
Aasim “oi homp ap pommnn imm mmm mooummt”
I “what?”
Aasim “oi homp ap pommnn imm mmm mooummt”

Then I understood – “I have a pond in my mouth” he was trying to say – with a mouth full of saliva!!!!
