here are some ideas if you want to try them out,
1)pick a list of shitty jokes that you know will bomb (we used to do muscle jokes, e.g. got your tickets? too the gun show haha, oh you like that one?, you hear about the escape at the zoo?, they're lookin for these pythons!! haha fuck yeah, ohh want some more? etc. etc.) just keep segueing into more and more shitty jokes until the group blows you out,
2)if your plan is to SOI a mixed set, you can just get permission first from the guy, or SOI and compliment the guy on a good job,
e.g. Hey guys, Just came over to hit on this hottie right here (point to girl) is anyone going to punch me in the face? yes? alright cool, well have a good day!
OMG dude great work on landing such an amazing hottie, how did you get such an amazing girlfriend? (at this point if it is not her bf and she is interested, she will blow him out, and you can just say sorry man

, and continue hitting on her)
