Well it depends dosent it. It always varies from girl to girl to what they like. Im probabley more tollerent with disgusting jokes and things than alot of my mates. I would just stick to normal jokes that arnt rude or likley to offend this girl. To make me laugh alot of the time me bf just tickles me or pokes me and says yeah beep beep. I no its random but that makes me laugh.
