you were having a bad day. And were sitting on your bed in your hotel room. Until you heard someone knocking. It was Billy! You didn't know what he wanted but howeever, he noticed you were sad. He climbs on your bed and jumps around on it. You asked him what he's doing...

"I'm just jumping on the bed! Don't be sad! Don't be sad!!"

he tried to cheer you up and pulls you on the bed with him, and now you both were jumping around together
