+### Other Scripts/Tools?
+
+Duh! Interpolation works like a shell, just call the scripts or binaries you want!
+Here we'll use a simple python script to spice things up!
+
+```python
+# favourites.py
+import sys
+
+print(" and ".join(sys.argv[1:]) + ",")
+print("These are a few of my favourite things")
+```
+
+```
+# My Favourite Things

+When the dog bites
+When the bee stings
+When I'm feeling sad
+I simply remember my favourite things
+And then I don't feel so bad
+```

+Output:
+
+```
+# My Favourite Things
+
+Gumdrops and Roses and Whiskers and Kittens,
