Maternity Tights

We're walking to work.

W: Don't walk so fast.
Me: I'm not. This is my normal pace.
W: Well I can't catch up with you any more. The tights I bought are too big. They keep falling down.

We walk slower.

Me: You could have bought smaller ones.
W: They're special maternity tights.
Me: Really? I thought the usual ones just expanded? That's why they use them in bank robberies.
W: (A look of incredulity) What are you talking about?

We walk a bit slower.

W: I suppose I could just put my pants on over my tights like I used to do at school sometimes.
Me: Did you?
W: Like superman.
Me: Heh! Now that's funny.
W: With a skirt over the top.
Me: I know! Superman. Heh!

I giggle to myself.
