An old man is sitting on his porch...

And sees two younger boys walking by with cat tails under their arms

Curious the old man asked where they were going with the cat tails.

"We are going to catch some cats"

"You can't catch cats with cat tails that's not going to work" says the older man.

And the kids go on their way. About an hour later the boys walk by the old mans house with a bunch of cats under their arms

The next day the same 2 boys are walking by with duct tape under their arms and the older man asks again what they are doin.

"We are going to catch some ducks"

"You can't catch ducks with duct tape boys that's not going to work" says the older man.

And the kids go on their way. About 2 hours go by and sure enough the kids walk by the old mans house with ducks under their arms.

The next day the old mans sees the same 2 boys carrying a plant under each arm, the older man stands up and asked what they had this Time.

"These are pussywillows"

The old man then stands up "I'll go get my hat."
