We weren't sure if we should laugh or just feel bad for these kids, but this video is definitely worth watching.

The staff at Pennsylvania's Center in the Woods preschool thought they would surprise their toddlers with a visit from Mr. McFeely, the delivery man character from the PBS Kids show "Mr. Rogers' Neighborhood."

The youngsters eagerly listened to Mr. McFeely as he sat in front of the classroom and introduced another special guest, Purple Panda, one of the costumed characters also on the PBS show.

Mr. McFeely stood up to welcome his friend, and as he entered the classroom, Mr. McFeely held Purple Panda's hand. The kids however, were not so welcoming.

Chaos immediately ensued. Screaming and crying children scattered to a far corner of a classroom, seemingly petrified by the sight of the Purple Panda, which was actually a person wearing a panda suit.

Confused, Mr. McFeely just told the kids to "stand right here" and as he waved at them. He then tried to calm them down by admitting that it's not actually Purple Panda but "somebody pretending" to be the panda. His words did not soothe the children.
