I've just checked on something I heard Frank Skinner say, and found it to be true.
Go onto Amazon and look for an aluminium baseball bat, then choose one. You can then see a list of items other people often buy with it. The list includes balaclavas and sports face masks!
"Honestly, officer, I'm only wearing this face mask because I keep getting bitten by midges. The baseball bat? Well, I need something to swat them with, don't I?"
