How to pipe "echoed" statements to be read by a second function TWICE?

Question

Suppose I have a script READER that goes:

#! /bin/ksh
read line1
echo "$line1 read!"
read line2
echo "$line2 read!"

I could do something from the command line like...

echo "schwifty" | READER

...which would successfully output "schwifty read!" but what if I want to input something for line1 AND line2?

if I could echo schwifty then echo schwifty2 from the same line and receive the following output:

schwifty read!
schwifty2 read!

...that would be perfect. IS there any way to accomplish this?

The above may not work though. But your best bet is to go look up command line commands. Such as from:
