My son and I have discovered the wonders of toilet plungers as toys.

1. They are far, far cheaper than any Dr Who toy.
2. They break much less easily.
3. They make great and formidable Daleks: the heft, weight and durability of a toilet plunger is great in a make-believe game of Dr Who.
4. With two, toilet plunger tennis is great, chucking balls and using the suction caps to catch them.
5. Flinging them against walls is great to see who sticks their most often against the wall.
6. They also unplug toilets.
