Come and get your tin foil hats right here! Brand new tin foil hats for any size head! One size fits all! Come and get them while they're hot!
If I may,I'd like to offer you some marketing advice. Consider bundling the foil hats with a trip to the secret island where Elvis ,the REAL Paul Mcartney,and Jim Morrison live.
Also I think "one size fits all" may be overkill. Basic pinhead size should pretty much do it.
