 Greg has been trying to line up a date with Sandra, but the date is on only if he can also arrange a date for her visiting cousin, Linda. Greg s friends assume Linda must be ugly (since Sandra has not seen her since before she entered puberty) and out of options, enlists Peter to date Linda (by donning a fake mustache and filling the role of fictional friend "Phil Packer"). Sandra and Linda quickly suspect they are being fooled but don t let on, planning to get revenge on their next double date. The only problem is that they hatch their plans in full view of Mike, Carol and his Mexican client.
