For this second entry, I’ll go with something that’s a bit less known, but still pretty weird. This is also something I like to bring up ever since I read it. According to DC Comics, (space) Gremlins speak German.
This is from Geoff Johns’s pre-New 52 run on Green Lantern, the one the brought back Hal Jordan as the main Lantern in 2006 after Rebirth. Specifically this is from issues #4-6 of vol.1 of Green Lantern. This is considered one of the overall best runs of Green Lantern, but that doesn’t mean it’s exempt from wacky stuff like this.
