What are pranks to play on my senile grandpa?

You could always set up a string of prank calls using a phone trick. Start by putting Grandpa’s ringtone on loop, followed by transferring the call to another line when he answers the phone. Record several messages on that line, such as a loved one saying they love him, followed by a silly joke or a prank. Wait for his reaction when he believes someone is really talking to him. You can also dress up in silly costumes and have hidden video recorders document his reaction to a monster or ghost in his own living room. For an extra scare, you can even record your voice telling him it was a joke so he thinks he is hearing things. For an extra surprise, you could always set up a series of prank decorations around the house!
