Is anybody familiar with the grown ups Improv playground? Thanks

I went on an audition for them a few weeks ago.

They seem like very nice people interested in having a good time, but I didn't really get the feeling that they were very focused. Halfway through our opening warmups, some guy walked in and the woman running our audition invited him in and spent most of the two hours having conversations with him.

Also about halfway through the audition we all had to stop to sing happy birthday to one of the auditioners, and sign his birthday card.

Unusual, to say the least.
