I do not like this kind of bet. A bet that no money nor anything is involved. I mean nothing is involved because one of you can decide not to fulfill the betting promise. Example is if your friend did not lose more weight and still decide not to pay for the meal? This can happen. I do not bet with people. I prefer to go to casino or bookie to bet instead.
well, since the whole idea was base on gaining weight like he said, which is absolutely Self-beneficial, I guess it'll be a better satisfaction if the said target is met, than a meal is served or paid for. (I dunno if you get my point?) Nevertheless, it is what it is... Lol
OP, we got a thread for pushups already, although it ain't on this board, but there's a good level of participation in there already... Would you like to make this official then?
