So far I only thought of skiing.
bassist is probably the only two syllable word that rhymes with racist
Because he only had two worms! Get it? Two of every animal on the ark, including worms. So, Noah couldn't catch many fish because he only had two worms. Simple math, my friend.
Just between you and me, only between the two of us

The ribs join at the back. In front they are connected to the thorasic basket, also known as the breast bone. Only the last two ribs do not join each other . They are the floating ribs.
Lower most two pairs of ribs (11th and 12th) are known as floating ribs because they are only attached to vertebrae but not to the sternum.
Neither those two groups only refer to animals! Vertebrates are animals with backbones, invertebrates don't have backbones.

Floating ribs are the last two pairs of ribs in the human ribcage, specifically the 11th and 12th ribs. Unlike true ribs, they do not attach to the sternum or to the cartilage of other ribs; instead, they are only connected to the vertebrae at the back. This anatomical feature allows for greater flexibility and movement in the lower back and abdomen.
Floating ribs are four atypical ribs (two lowermost pairs, XI-XII) in the human ribcage. They are called so because they are attached to the vertebrae only, and not to the sternum or cartilage coming off of the sternum. Some people are missing one of the two pairs. Others have a third pair. Most, however, possess only two pairs. Their position can be permanently altered by a form of body modification called tightlacing, which uses a corset to compress and move the ribs.
Only the true ribs are attached to the sternum the false ribs (3) and the floating ribs (2) are not directly attached. The flalse ribs are attached indirectly via cartillage and the floating ribs are not attached at all.
The ribs that don't connect to the sternum are known as floating ribs. There are two pairs of floating ribs, specifically the 11th and 12th pairs of ribs. Unlike true ribs, which attach directly to the sternum, and false ribs, which are indirectly connected, floating ribs are only attached to the vertebrae in the back and do not have any anterior connection. This anatomical feature provides flexibility and protection to the lower back.
