What Is National Tell A Lie Day?
National Tell A Lie Day lands on April 4th - three days after April Fools’ Day. Think of it as the extension round for anyone who did not get their pranks in on time. The holiday is completely lighthearted and meant for harmless, obvious fibs that make people laugh.
This is not about deception. The best Tell A Lie Day posts are the ones where nobody is actually fooled. The joke is in the absurdity - claiming you ran a marathon before breakfast, saying your cat wrote your novel, or insisting you invented a food everyone already knows.
Why #NationalTellALieDay Works on Social Media
Humor drives engagement on every platform, and Tell A Lie Day gives creators a built-in excuse to be silly. The hashtag trends reliably every April 4th because the concept is simple, participation is easy, and the content is fun to scroll through.
Posts using #NationalTellALieDay, #TellALieDay, and #TellALie tend to get strong comment engagement because followers want to play along. They will call out your lie, add their own, or debate which statement was actually true.
Content Ideas That Drive Engagement
Two Truths and a Lie. This is the classic format and it works every time. Share three statements about yourself - two real, one fake - and ask your audience to guess the lie. Comments will pour in.
Obvious celebrity lies. Post something absurd about a well-known person or brand. “Just found out the Eiffel Tower was originally built in Ohio and shipped to Paris.” The more ridiculous, the better.
Product or brand lies. If you run a business account, announce a fake product that is clearly a joke. A pizza shop announcing they now deliver to the moon. A pet store claiming they have started stocking unicorns. Keep it on-brand but obviously fake.
Lie about your pet. Pet content already dominates social media. Add a silly lie - “My dog just finished his PhD in astrophysics” - and pair it with a cute photo. Easy engagement.
Historical “facts.” Make up an absurd historical claim and present it deadpan. The format invites people to share it, laugh at it, or one-up it with their own fake fact.
Best Hashtag Combinations
Stack these tags to get maximum visibility on April 4th:
- #NationalTellALieDay - the primary hashtag with the most search volume

- #TellALie - broad and conversational, works year-round for humor posts
- #NTALD - abbreviation used by repeat posters and brands
- #AprilFools - catches residual traffic from people still in prank mode
- #TwoTruthsAndALie - perfect if you are using that format
- #JustKidding - good add-on for obviously fake announcements
Platform Tips
Instagram: Carousel posts work great for Two Truths and a Lie - put each statement on a separate slide with the reveal at the end. Reels with a dramatic “lie reveal” format perform well too.
X (Twitter): One-liner lies get the most retweets. Keep it short, deadpan, and let the absurdity speak for itself. Quote-tweet chains where people add their own lies can go viral.
TikTok: The “tell me a lie” sound trend resurfaces every April. Duet and stitch formats let other creators build on your content, which multiplies your reach.
Facebook: Two Truths and a Lie posts in groups generate massive comment threads. Post early in the morning to catch the algorithm before the feed gets crowded.
