Not sure if this is fact or fiction but, I heard a story one time about a very well known DPE at my airport who was on a checkride with a commercial candidate in a C-172RG when they couldn't get the gear down she told the candidate to open the door and reach down to pull the gear out "manually". Needless to say the student did just that while the examiner held onto the candidate pants so they wouldn't fall out. Landed just fine.
