Ha! Ha! Ha!

..that's what it is. No plot, just a series of increasingly bizarre sight gags strung on one premise: Betty Boop tries to treat KoKo's toothache with laughing gas, and as they're both overcome by the fumes and forget to turn the machine off, the gas pours out into the city. Typewriters, cars, mailboxes, bridges and finally a whole cemetery full of tombstones grow mouths and burst into uproarious (in the tombstones' case, echoey and ghostly) laughter. Finally the giggling KoKo and Betty return to their ink bottle, which too grows a face and begins to laugh. Mere description can't give any idea how *weird* this cartoon is..don't miss the knock-down-drag-out duel between a pair of pliers and a set of false teeth!
