Having had his parents do everything for him from a young age, Iain takes his bus mates to Edinburgh to him help give something back to his parents. They have a go at curling with Iain's dad for a little father son bonding time, go full 'Celt' and throw Mr and Mrs Stirling their very own cèilidh and they visit the local animal shelter where they make their very own doggy calendar...and yes, Joel gets naked. Again.
