Number Jokes

Santa and Banta were sitting in a hotel and started chatting. Santa tells a number and Banta laughs, then Banta tells a number then Santa laughs. This practice continued for a long time when a waiter saw this and reported to the manager. The manager notices them for a while and then asks them the reason for their joy. To which Santa and Banta reply together "We remember a large no. of jokes. But due to shortage of time we do not tell in detail and just tell the said number of the joke. The other one remember the joke by number and laughs".
