i don't take French - but this is a line my friend taught me
and I said it to this French guy as a joke/dare - so it might not be
a pick up line, but it sure gets you interesting looks after you
whisper it seductively in his ear and walk away as he looks confused:
"Je a pataloon"
of course some other people respond with "too bad"
o by the way, it means "I have pants"
