Abstract: What do these three subjects have in common? Nothing, but I
couldn't choose between them. I will briefly explain why no galaxy
clusters that have currently been measured show tension with the
standard cosmological model, despite recent claims. I will then
briefly show why a possible detection of the integrated Sachs-Wolfe
effect does show significant tension. Finally I will briefly explain
how the strictest form of the Lyth bound can be violated, thus
allowing for small-field models that can generate observably large
primordial gravitational waves. I will present an example of such a
model that fits all current data.
