" To make it more frustrating for the birthday boy or girl, you can have a huge gift box and in it you can place two or three other gift boxes and in the smallest gift box you can place these two batteries.
Another hilarious 50th birthday gag gift can be this clock, which runs backwards. When you will present the birthday girl or boy with it, the person will quite obviously think that it is a usual lock. But he would be surprised to know that this is not any usual clock but it runs backwards! There would certainly be no end to their surprise.
Bug In Ice Cube
Yet another birthday gag gift can be this bug in the ice cube. Enclosed inside a clear cube of ice cube there lies a huge dead fly. You can put it in the birthday boy's drink and can wait to hear those shrilling yells. Once they will get to the bottom of the drink they will notice this fake ice cube.
Of course as you look to celebrate a fiftieth birthday a big part of the celebration is the party that you throw in the honor of the person. Turning 50 of course is not really the arrival of old age but the joke lies in treating this birthday as such. One gag is to have all of the paper wares and decorations done up in black. Add black balloons will provide a finishing touch and you will be all set for a 50th birthday bash!
Other humorous gift ideas for a 50 year old can be something which reminds them of their younger years. Large blowups of the pictures from the yesteryears or a shirt that is styled very differently from today would definitely be a good idea.
