SCHOOL OF ROCK star Jack Black took a crash course in birthing techniques to prepare for the birth of his first child, but immediately forgot everything he learned when he went into the delivery room. The star was busy with work and didn't have time to take a proper Lamaze training course with wife Tanya Haden, so they had to cram it all into one session. He explains, "We did the Lamaze, the traditional Lamaze. But I was actually working doing a lot of promotion for NACHO (LIBRE) and out filming a movie in New York. "We actually had to squeeze all of the Lamaze into one power session, because it's supposed to be like 12 hours of Lamaze but we got all of the information in one super-session. "Then when it came time to deliver, I just forgot all of it. I was like, 'Breathe! I think you breathe on the downstroke!' "She was looking at me to be the powerful anchor and I was just a blubbering, weepy idiot. It was very emotional for me. "I'm just so glad we made it through and that the baby is all beautiful and looks like her, luckily, because with the genes from me, it could have been a pot-bellied pig that came out of there."
