"[discovers Gossamer] Uh-oh. Think fast, rabbit. My stars! Where did you ever get that awful hairdo? It doesn't become you at all. [sits the monster down and starts brushing its hair] Here, for goodness' sake, let me fix it up. Look how stringy and messy it is. What a shame. Such an interesting monster, too. My stars, if an interesting monster can't have an interesting hairdo, then I don't know what things are coming to. In my business you meet so many interesting people - Bobby pins, please - but the most interesting ones are the monsters. Oh, dear, that will never stay. We'll just have to have a permanemanent. [puts some dynamite on the monster's hair like rollers] Now, I've got to give an interesting old lady a manicure, but I'll be back before you're done. [leaves as the dynamite explodes, leaving a huge bald spot on the monster's head]"

"Oh, for shame. Just look at your fingernails. [rushes off and immediately returns with manicurist's table and equipment and begins to do the Gossamer's nails] My, I bet you monsters lead interesting lives. I said to my girlfriend just the other day - Gee, I'll bet monsters are interesting, I said. The places you must go and the places you must see, my stars! And I'll bet you meet a lot of interesting people, too. I'm always interested in meeting interesting people. Now let's dip our patties in the water! [dips Gossamer's hands into two bowls, where 2 mousetraps snapped shut on them]"
