One day as Dave was riding on a crowded bus with
standing room only, the bus stopped and an elderly
lady got on carrying a large picnic basket.

She stood right in front of Dave and grabbed the
overhead rail so the picnic basket was above Dave's
head.

Being a gentleman, Dave offered his seat to her.  She
quickly declined as she was only going a short distance.

Soon the picnic basket began to leak.  Then Dave felt
something drop on top of his head and into his lap.  As
he looked up it hit beside his nose and ran down across
his lips.

Dave tasted it, looked up at the lady and asked,
"Pickles?" 

She replied, "No, no, puppies".
