Ask him were his eyelashes are
Ask him how expensive single fireproof contact lenses are
Say " Who's the lucky girl?" and point to his ring
Give him and the ringwraiths pet names
Get him drunk
Start singing elvish ballads and recite their poems when he's around
Tell him he'll make a great villian someday
Have a staring contest with him and win
( Some are lame but that's ok)
