HAILING TAXIS

When I was a kid, I preferred Fleer's Double Bubble rather than Bazooka.

TONIGHT, during a downpour, I actually told the following joke which I remembered from the inside wrapper of Double Bubble bubble gum:

WHAT'S WORSE THAN RAINING CATS AND DOGS?

HAILING TAXIS!

I was probably about 10 years old when I unwrapped that joke;  Mother had to explain it to me because we had no taxis in our town and I didn't understand the "HAILING" pun!
