Whenever I claim to be funny people give me the same look my girlfriend gave me when I told her she's drawing her eyebrows on too high... She looked surprised.
Recognising - pretty good, sometimes it does go over my head though.
Delivering - not bad I suppose, both our humour is very dark, sometimes fast (faster the better too) but those who take it enjoy it. Me and husband can bounce it back and forth with each other.
