I lost that round. I didn't do well!

A town in medieval Italy had a spring that the town had grown up around. The spring had medicinal properties and the villagers built a stone lined pool to collect the spring water. After many years the town fathers decided that, although the spring attracted many visitors, they needed a new fountain and larger pool to show off their medicinal spring. They hired a noted sculptor/fountain designer to design and construct their new fountain. He accepted, and he designed a fountain that met the town fathers approved. The town fathers instructed him to construct it behind canvas covered scaffolding because they wanted their villagers to be as impressed with it as much as visitors would when it was unveiled. The sculptor worked with his crew behind the scaffolding for several months, maintaining the secrecy the town fathers requested.

The night before the unveiling, the town drunk was staggering through the town center, tripped, fell, and rolled under the scaffolding. He climbed to his feet, but, astonished by the beauty of the new fountain, staggered backwards into the scaffolding, rebounded to the fountain, fell over the outside wall and fell into the pool. His drink bottle fell out into the pool and shattered, spilling his licquer into the pool. Very soon the water got colder and the drunk scampered out of the pool and turned to look. Very soon he saw the spraying water and pool froze over, which, as you might expect, surprised him. The night watchman, having heard the commotion at the new fountain, came around the scaffolding, saw the drunk and the frozen fountain. The drunk turned to him and said "Absinthe makes the font grow harder".

Our school's name starts with 'CHA', and we'd love a short, memorable friend-group name with a clever pun using those letters — something with a double meaning or a sound-alike twist.

A rival friend group has been called Ice for over a year, but we want a name of our own, not a copy of theirs. What's the best CHA-based pun you can come up with? If you've heard a great friend-group name that uses a similar trick, we'd love the inspiration too. Original suggestions are welcome!
