Awww, you mean Ratchet never gender-swapped Sideswipe and Prowl in canon? :)

*snicker* Oh dear. Now I have a new threat to add to Ratchet's repetoire of tirades. Now they can end with "--do this again and I'll rebuild you into a femme!" Probably not so effective on Sideswipe, as you've demonstrated, but I do think Sunstreaker would be appropriately horrified. ^_^ Also a threat Ratchet is not likely to use while any actual femmes are within hearing distance.
