Sexual double entendre at the 43:00 minute mark?

Ms. Blake asks Dr. Garth who has s going to tie his tie. He replies "I've been tying my own tie since I was 16." Hmmm...? Old crotchety Ms. Peabody attempts it but she's sweating and a bundle of nerves. Finally Ms. Blake tells her how to do it. Do you think there was some pre-code inside sexual innuendo going on here? Can't help how I took it but I believe so...
