(Shelly and Kevin have been dating for awhile now and neither Shelly's or Kevin's parents know of their relationship. That is until stan and Kenny accidentally walk in on the two cuddling. Shelly doesn't see them but Stan takes a picture of the two then Shelly sees them)

Shelly: stan I swear to God if you tell mom and dad I'll kill you!

Kevin: hi stan, hey kenny (he waves)
