I love, love, love this episode! I think it's hysterical.
When Chandler and Joey leave Ben on the bus, it's so funny... and then they can't figure out which one is Ben, so they flip a coin. And then when they get back to the apartment, he doesn't cry when Monica holds him... oh wait... whew! But Ross finds the city property stamped on his butt. I love it!
Then Pheobe gets kicked out of Central Perk, and starts playing on the street! Haha! It's Smelly Cat!
And Ross has an allergic reaction to the kiwi pie, and is terrified of shots, so he comes up with the "thsqwuirt gun," plan, but ends up breaking Monica's hand! What a hilaroius episode!
