Can't find video of it, but a comedian named Gary Valentine did a special for "Comedy Central Presents" about 12 years ago and in his act he was talking about awkward things during puberty and one of his jokes was about how age 12 is that weird age due to girls going through puberty before boys do.
"Ya know, the boys are like 4-3. The girls are like 6-7". Thought that was funny.
Can't find video for this either, but Johnny Sanchez, a short comedian, did a CCP around the same time and he had a whole piece about being short. Things like:
- Using a flare in a nightclub to get a woman's attention
- Jumping in the air to high five your date
There's a lot more, but he keeps it tasteful. Pretty funny guy.
Lastly, I remember one of Patton Oswalt's opening jokes to one of his specials was going off to live in a town full of only people with dwarfism, so that him coming to town would be "Attack of the 5 foot 5 guy" lol.
