My controversial self can't wait for this...
Alcohol at football stadiums
the European Union
small countries that serve no point (Liechtenstein, Andorra, San Marino, Vatican City to name some)
People that just follow what their obviously crazy partner says (i.e. my grandfather, my neighbour etc. etc.)
Bikes on the road right next to the official bike path (either on the roadside barriered off or on the pavement - however only where a cycle route runs through it!)
Road signs that are hidden behind trees at odd angles
Futons
Trains without toilets
the Class 196's destination board. Very odd
Commemorative coins
