Nominating my son-in-law.
Visited for a week and sensibly brought his bike.
Leaving Sat on the ferry, he packs car, carefully taking wheels off bike and putting frame in first. All other luggage (lots when you have a toddler) added.
We leave them at ferry port and drive home. 5 min after driving home, phone call. Wheels left behind.
Cue dash to ferry port, arriving just in time (daughter is waiting in the port car park, SiL has driven onto ferry). Daughter then runs after car, one wheel in each hand.
