I never really liked the chicken jokes either. They read like the family circus, a big gap where a joke should be. I will say that dead baby jokes sometimes read like there isn't a joke there but I think those are awesome hillarious. Like:
Whats worse than 3 dead babies in 1 trash can?
1 dead baby in 3 trash cans!
And I was jokin about liking to explain my jokes, I just say that when material bombs horribly, because what are you supposed to say at that point?
I also wait a full 5 minutes after lamers tell really obvious jokes then once everyone forgot about it burst out and go "HA! I just got it! Man, thats great!".
Same thing goes for clapping at concerts, 'specially the sucky ones...wait...wait...ok they're done, start clapping and shouting when they start playing again.
