You can't hide a 400 pound man

 Where did he go 

Is the 400 pound man still upstairs

 With this other person 

One animal is on the loose

 Behind the mirror in the bathroom

 Like their pets 

These people have

 Animalistic behavior 

Try me on

 Yo 50

Your chances

 50-50

 In this building 

I'll be back
