With a show based around time travel,
All this being said, the duo certainly pull some top-notch comedy out the bag, both old-school and ingenuitive.
The need for such throwaway gags may well stem from a conceit both a little ill-fitting and overly-odd. Not only do the two feel the need to explain the ins-and-outs of their time-hopping technology, but this conceit is further complicated by the introduction of unnecessary throughlines: the pair, for example, centre their journeys around family members’ past and present. Not only does such high-concept stuff take plenty of time in the explanation, but it likewise means the sketches themselves become very tenuously linked to the core conceit(s): I still don't understand why a conversation about confidence would lead the two to visit a provincial mayor opening a hospital, nor why a sketch featuring Seal and Heidi Klum - in its own right incredibly funny - must be made to fit the familial mould of the show once again. To be sure, the pair caveat the batty ideas with (more) metahumour, "try not to give this too much thought because we haven't" - such a statement is a little more apt that it was meant to be.
All this being said, the duo certainly pull some top-notch comedy out the bag, both old-school and ingenuitive. An old-fashioned prop comedy skit set in a library leaves its audience in stitches. Likewise, the pair push the envelope to hilarious effect even when they're offstage, with a running bit using Siri, and a madcap audio tour through a showhome that is wonderful in its ability to constantly wrongfoot the audience throughout its running time.
Both parts of this outfit are eminently talented, and it is only because they produce such an awe-inspiring amount of content that I'm given so much to critique. I'd certainly recommend seeing them to anybody:the pair are immensely likeable, and their show certainly leaves its audience on a high - I'd only suggest these time travellers might want to pause for a second and bring their concept down a level or two.
