Bruno Mars points out a glaring inconsistency in the lyrics to one of his biggest hits

Sometimes looking back at your own work can be a somewhat humiliating experience -- even when it is pretty impressive and has afforded you numerous awards.

Singer Bruno Mars just proved that on Twitter, where he pointed out a lyric that doesn't actually make sense.

When Twitter account Chart Data — which tweets facts and data about the music industry — pointed out that Mars' hit song "Grenade" made number one eleven years ago, Mars' retweeted his observation about an inconsistency in the lyrics.

In case you need a reminder, or if you for some reason just weren't paying attention in the years 2010-2011, the lyrics to "Grenade" go "Should've known you was trouble / from the first kiss / had your eyes wide open / why were they open?"

As anyone capable of logical thinking can probably figure, Mars would have no way of knowing that his lover's eyes were open, had he not kept his own eyes open. Whoops.

Oh, well. Bruno, we'd still catch a grenade for you.
