Potty Training Joke

Little Johnny was just being potty trained and his mom tried this new method with 6 steps:
1. Unbutton pants
2. Pull pants down
3. Pull foreskin back
4. Pee
5. Push foreskin forward
6. Pull pants up and button up

She walked past the bathroom one day and heard Johnny going 1,2,3,4,5,6 and she was thinking she did good.

Then she walked past the next day and heard him saying real fast 3-5,3-5,3-5...
