Series 1
- In the first episode, Jonathan briefly forgets that this is a show about dancing, not singing.
- Everything about Rubber Chicken, who just owns his persona, moving his arms like people do when impersonating chickens, and constantly making clucking noises. In one episode, Joel throws some seeds onto the floor for him, which he pretends to eat.
- In Episode 3, Joel speaks in an over-the-top southern accent as Scarecrow is about to leave the stage after her performance. Mo tells him to never speak like that again.
- David Walliams joins the panel as a guest judge in Episode 5, and guesses Donald Trump for one of the contestants.
- How Oti works out who Knickerbocker Glory is: she recognises the way he sashays off stage after his performance.
- A pigeon showing up at the end of Carwash's semi-final performance to give him a cone of chips.

Series 2
- Astronaut's clue package briefly features a white van. Peter Crouch then suggests a long list of celebrities whose surname contains the prefix "van", before guessing ... Denise van Outen (who had previously competed on Singer as the Fox), even though Astronaut is clearly a man.
- Amusingly, when Astronaut's identity is revealed, it turns out that Peter was right about the "van" prefix. He just didn't realise that the clue was referring to a fictional character.
- Episode 4 opens with the judges joining the contestants in a group dance number. At the end, Jonathan falls over, much to the other judges' and Joel's amusement.
- One of Sea Slug's clues is about their "bom bae". Jonathan has no idea what that means, and Oti explains that it is a cool way of calling someone 'babe', much to his horror.Jonathan: It is not cool to mangle the English language.
- In episode 5, Oti starts to believe that Pearly King might be Bruno Tonioli (he is). Jonathan then reminds Oti that she once claimed Pearly King wasn't a professional dancer. This immediately leads to Oti backtracking furiously on her comment, all while Pearly King mimes digging a hole on stage.
- Pearly King in general does a lot of suggestive movements around Joel after his performances, and also has No Sense of Personal Space. In one episode, Joel even notes that it will be awkward after his identity is revealed.
- In episode 6, Joel claims to not have a stunt double, before doing a few backflips... except his face isn't visible and due to the show being pre-recorded, it's easy to tell that it is in fact a stunt double, who then walks past in the background afterwards.
- Candlestick's performance to "Finesse" is a partner dance. When the dance is finished, his partner leaves the stage — and Candlestick tries to follow her, even when Joel stops him and walks him back to center stage.
- In the semi-finals, Oti continues to suggest that Pearly King is Bruno Tonioli. After Pearly King's performance in the Dance Jam, guest judge John Bishop agrees with Oti's suggestion ... except, he thought that Pearly King was Anton Du Beke. Pearly King reacts by dramatically fainting on stage.
- John Bishop's final guess for Odd Socks' identity is Jane, a girl who used to be his classmate.
