The first empty seat Len spots is in the middle of a row, and he makes his way to it without bothering to look for one located more conveniently.
"Sorry; thanks; excuse me; sorry; whoops; excuse me; ta; sorry!"
Upon reaching the seat Len finds it flanked by two burly men, arms folded and legs like tree trunks, leaving almost no space for Len.
"Pardon me; if I could just; excuse me; just a moment." Len's attempts to squeeze into the seat are met with stony faced silence.
Len mutters to himself, "If I could somehow get in from the top, there'd likely be enough room."
Without thinking twice, the dwarf pulls himself up on to the back of the seat in front, and in the same movement leaps from it, performing a somersault and simultaneous 180 degree spin, landing with arms and legs folded between the two men.
Unfortunately for Len, instead of landing on the seat of the chair he becomes wedged between the men, suspended in the air and legs dangling. Unable to elicit a reaction from either of them, Len shrugs and waits for the proceedings.
