A man leaves his mistress and asks what to give her as a souvenir.
She answers:
"A penknife, but a very good one.
The guy scoured the whole city, found her a knife, just super, brought it, gives it back.
She opens a drawer, and there are a lot of knives there. Well, the guy is interested, he
asks:
- Darling, why do you need so many knives?
She's dreamy:
- You know, I won't always be young and beautiful, and what boys
won't do for a penknife...(c)
