0 Year Old Birthday Candle Joke

If you ever feel useless, remember there's a candle to turn 0 years old
this is why shampoo has instructions

This meme opens with top text reading 'If you ever feel useless, remember there's a candle to turn 0 years old'. The main image shows a supermarket shelf selling individually-packaged, number-shaped red birthday candles, including a standalone number 0 candle priced at 0.75€ alongside other number candles like 1, 2, 5, 6, etc. At the bottom, the punchline text reads 'this is why shampoo has instructions'. The joke pokes fun at the pointlessness of a separate 0 birthday candle (since 0-year-olds do not need an age-shaped candle for a 0th birthday) while also joking that such unnecessary products only exist because there is demand from people who need even the most obvious things explicitly provided, hence the punchline referencing that even simple products like shampoo require instructions for this same reason.
