Most things aren't infinite or extreme, though. Almost by definition, most phenomena aren't extreme phenomena.
In practice when modeling you are almost always better not assuming normality, and you want to test models that allow the possibility of heavy tails. The CLT is an approximation, and modern robust methods or Bayesian methods that don't assume Gaussian priors are almost always better models. But this of course brings into question the very universality of the CLT (i.e. it is natural in math, but not really in nature).
Some things with heavy tails:
token occurrences
comment thread upvotes
startup IPOs
social follower counts
network latency
github stars
git diffs
power station size
weather events
