Fun, outgoing people, can I ask you a teeny thing?

kay, so imagine your walking through the mall & you see a friend (girl or guy) you havent seen for a couple of months. you miss them really much but well, daaang, you see 'em at the mall. what if yur kinda awkward & dont know what to say except the good old "how are you?" statement. what should someone say to a friend they havent seen for a while so they could have a rather fun & random convo? like go up to them & bear hug them or something & be like "oh hey fiesty person, hide in narnia for all this time?" idk. & then what to talk about..? :) im 15 too
