7/7 - all aboard the bandwagon!
Preferably one with large, well padded seats, little holders for Kleenex (for dealing with RIP threads), small notebooks for capturing poetic thoughts that flit through one's mind, space for storing food (particularly for the foodies) and spare underwear for the delicate females.
There is also an oft-seen variant of the classic Bandwagon: that of the 'Jock Haters Bandwagon'. To hop aboard, one must refer to Gordon Brown as Broon, make many, many references to Irn Bru, meanness, cold weather and meanness. Again.
Rule 31 applies at all times whilst embarked.
