“Why do birds sit on power lines, but if I touched a power line I would be electrocuted?”
The show has not technically started yet, but Tom Knowles and Jeff Parsnips did say that they wanted us to ask questions. So, the young audience member who wants to know about power lines is just following instructions. Gamely, both of the titular dads stop the pre-show in its tracks to give him their full and immediate attention. Jeff works through an explanation about how electricity needs to be grounded before it can complete a circuit. Tom suggests it’s something to do with what bird feet are made of.
“... Do you think birds’ feet are made out of rubber, Tom?” Jeff asks.
“Probably.” Tom answers, with the kind of dead-pan earnestness that will be familiar to dad-havers everywhere.
It’s this combination of Tom and Jeff’s genuine engagement with kids’ curiosity, and a riotous side of Kiwi dad humour, that makes But Why, Dad? so very charming. Even more impressively, they mostly deliver the show through the medium of musical comedy.
The story is loosely centred around a son asking his dad a series of difficult questions, which become prompts for comic songs. Together, Tom and Jeff tackle topics like overwhelming emotions, the power of asking ‘why’, and lesser-known words you could put in an alphabet song (B is for Barracuda!). It’s sweet, goofy, and heartfelt, with tonnes of laughs, loads of opportunities for the kids to join in, and plenty of humour for the parents too.
The show does have a villain: an AI robot who offers to answer the child’s questions when dad starts to struggle. It speaks from its clinically smooth screen in a clinically smooth American accent, in stark contrast with dad’s stumbling Kiwi bloke mannerisms and mismatched socks. This topical conflict comes down to a delightfully silly resolution, which celebrates the many joys of ‘asking dad’ when you have a question.
