PowerPoint: I will never recover

I just attended an online presentation given by a large software firm outlining the details of their next release.
48 slides. 1 hour.
My brain walked away after slide 2. Most of the room was laughing and telling jokes by slide 5.
Was it effective? Did it communicate the message? Did it make me more confused about their offerings? Was I motivated to buy?
They need Cliff and the BullFighters. On retainer. Full-time.
