Whose foot?

Hello doctor,I’ve got that athlete’s foot in my mouth again
You must have a big mouth
But doctor,I need some ointment
I’d try rodent repellent if I were you
Look at my notes and see what you find
Ok, you have cystitis and now you have oral thrush
I hope it’s not alive
How could you breathe if a bird was in your mouth ?
Through my nose.I don’t think a bird would go up there
I’ll send you some gel, oral gel.
If I don’t use it all it might be useful
For what?
Doctor, please don’t say amything
But we’re on the phone!
You don’t have to talk though
Be off
