People who use public transport often bring a book to keep themselves entertained.
However, at least 35 commuters tried a different trick to stay busy, bringing a sex toy onto the Tube, bus or tram.
The items were collected by Transport for London (TfL) after they were left by hapless owners.
Despite many viewing sex toys as a little embarrassing, 15 brave Londoners came forward to collect their lost property.
Clearly, some see Viagra as more sensitive because four passengers lost their erectile dysfunction drugs and never collected them.
TfL generally donates the lost items to charity if they’re not collected in three months.
The city-owned network has raised £1m from the sale of the items.
However, some are simply disposed of, according to the Evening Standard.
It is probably not advisable to use a sex toy on public transport.
Much more tame items were also found left on the network, including 744 crutches and 135 wigs.
