In no particular order (just as I think of them)
"I don't miss much you know"
"The truth will out"
"That's like .... (then gives an example) ... - this might go on at some length, I've got others......"
"I don't want to bore you"
"I'm not stupid, you know"
(play with the inflection)
"I love all forms of communication, expression, I love language, and Maths is just another form....."
<puzzled expression, almost apologetic, perhaps more annoyed or frustrated> "But I Have" or "But I am"
or "Yes I could"
