More about weirdeness and randomness and annoying-ness (?)
go up to someone in a shop and randomly say something out loud to them like
-(Walk up) You see!? You see!? I like chicken Banna Apple Cream Pie Sandwiches and wot do u like Cheese"!
and wen they say something like
-"WTF u dont know me wot I like!" say something like "Oh shut up we both know Im right your wrong Im Sane your crackers Im Hubba bubba you are Juicey fruit"
Just be totally random and annoying make it last at least 2 mins and wen you have had enough of the other person has just say -
"You looked like someone I knew sorry" BONUS - as soon as your convo is over immediately go onto someone else right next to the person you just annoyed
