  It was shown by Gruslys, Leader and Tan that any finite subset of
$\mathbb{Z}^n$ tiles $\mathbb{Z}^d$ for some $d$. The first non-trivial case is
the punctured interval, which consists of the interval $\{-k,\ldots,k\} \subset
\mathbb{Z}$ with its middle point removed: they showed that this tiles
$\mathbb{Z}^d$ for $d = 2k^2$, and they asked if the dimension needed tends to
infinity with $k$. In this note we answer this question: we show that, perhaps
surprisingly, every punctured interval tiles $\mathbb{Z}^4$.
