The perfect chemistry pun doesn't exi-- oh wait, there it is. When metals and non-metals bond, they form ionic compounds by transferring electrons. So the bond is literally "ionic" while the punchline is ironically "I-onic." Just like how my lab partner promised to label the solutions but didn't. Trust issues in chemistry are real. Electron transfer is basically just atomic commitment issues.
