so which part do you stick on your nose?
You could try sticking the small end of the tampon up you rnose and letting the rest dangle. When people ask you about it, go Monty Python on them:
Q: What's that hanging from you nose?
M: Whatever do you mean?!
Q: You have a lump of something on a string dangling from you nose.
M: PREPOSTEROUS!
Q; No, REALLY! (reaches for tampon) Let me show you.
M: (jumping back and taking umbrage) Keep you hands OFF me sir! You are CLEARLY INSANE!
and so forth.
